[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 26, 2023, with application number 202311818255.4 and application name "A Voltage Stabilizing Circuit and Adjustment Method", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of electronic technology, and in particular to a voltage stabilizing circuit and an adjustment method. Background Art

[0004] A single event effect (SEE) occurs when a single heavy ion or proton with sufficient energy impacts a semiconductor device, causing device malfunction or failure. Common SEEs include single event upset (SEU), single event functional interrupt (SEFI), single event transient (SET), and single event burnout (SEB).

[0005] With the rapid development of aerospace technology, the integration density of integrated circuits has become increasingly higher, and various electronic components are widely used in spacecraft. The space radiation environment refers to high-energy radiation from galactic cosmic rays, solar cosmic rays, and the Van Allen radiation belts. When spacecraft operate in this environment, electronic components within the spacecraft may be affected by this radiation and experience single-event effects, which can lead to malfunctions.

[0006] Low dropout regulators (LDOs) in spacecraft typically serve as tertiary power supplies for components such as chips. If the LDO is affected by space radiation and experiences a single-event effect, resulting in output voltage fluctuations, this can cause subsequent components powered by the LDO to malfunction or even burn out, leading to spacecraft failure and significant economic losses.

[0007] Therefore, how to improve the stability of LDO output voltage is a technical problem that needs to be solved urgently. Summary of the Invention

[0008] The present application provides a voltage stabilizing circuit and an adjustment method for improving the stability of an electrical signal output by a power supply device or a power supply component.

[0009] In a first aspect, the present application provides a voltage stabilizing circuit, which includes a sensing module, N feedback modules, N reference signal modules and N adjustment modules; wherein the N feedback modules are respectively the 1st feedback module to the Nth feedback module, the N adjustment modules are respectively the 1st adjustment module to the Nth adjustment module, and the N reference signal modules are respectively the 1st reference signal module to the Nth reference signal module; N is an integer greater than 2, and i is an integer greater than or equal to 2 and less than N; the input end of the i-th feedback module is connected to the output end of the i-th reference signal module and the sensing module, respectively, and the output end of the i-th feedback module is connected to the input end of the i-th adjustment module; the N adjustment modules are connected in series, and the output end of the N-th adjustment module is connected to the input end of the sensing module.

[0010] In the voltage-stabilizing circuit provided in the embodiments of the present application, the output ends of the N feedback modules are connected one-to-one to the input ends of the N adjustment modules. Therefore, when a component in the voltage-stabilizing circuit experiences a single-event effect in a radiation environment, the N adjustment modules can adjust the electrical signal in the voltage-stabilizing circuit based on the feedback signals output by the N feedback modules. This can eliminate fluctuations in the electrical signal output by the voltage-stabilizing circuit due to the single-event effect, thereby enabling the voltage-stabilizing circuit to output a stable electrical signal. This effectively improves the radiation resistance of the voltage-stabilizing circuit, thereby enhancing the reliability of the voltage-stabilizing circuit.

[0011] In the embodiment of the present application, the electrical signal in the voltage stabilizing circuit may be a voltage signal or a current signal.

[0012] The voltage stabilizing circuit provided in the embodiment of the present application can be set in a power supply device (such as an LDO power supply in a spacecraft), thereby effectively improving the stability of the output voltage of the power supply device, thereby improving the working stability of the powered device or powered components.

[0013] In one possible design, the first adjustment module is used to adjust the input electrical signal of the voltage stabilizing circuit according to the first feedback signal, and output the first electrical signal; the i-th adjustment module is used to adjust the output electrical signal of the i-1-th adjustment module according to the i-th feedback signal, and output the i-th first electrical signal; wherein the N-th first electrical signal is the output electrical signal of the voltage stabilizing circuit; the sensing module is used to collect the N-th first electrical signal and output N second electrical signals; the i-th reference signal module is used to generate the i-th reference signal; the i-th feedback module is used to generate the i-th feedback signal based on the i-th second electrical signal and the i-th reference signal, and the i-th feedback signal is input into the i-th adjustment module.

[0014] In this design, the feedback module can generate a corresponding feedback signal based on the electrical signal output by the voltage stabilizing circuit and the reference signal, and input the feedback signal into the adjustment module connected to the feedback module, so that the adjustment module can adjust the output electrical signal of its preceding adjustment module according to the feedback signal, so that the voltage stabilizing circuit can output a stable electrical signal.

[0015] In one possible design, when the j-th feedback signal fluctuates, the N-1 feedback modules other than the j-th feedback module among the N feedback modules generate N-1 feedback signals based on the j-th feedback signal, and the N-1 feedback signals are respectively input into the N-1 adjustment modules other than the j-th adjustment module among the N adjustment modules; wherein j is an integer greater than or equal to 1 and less than N; one feedback module corresponds to one feedback signal, and one feedback signal corresponds to one adjustment module; the N-1 feedback signals are used to adjust the output electrical signals of the N-1 adjustment modules so that the fluctuation value of the output electrical signal of the voltage stabilizing circuit is less than a preset value.

[0016] In this design, when the j-th feedback signal fluctuates, the N-1 feedback modules other than the j-th feedback module among the N feedback modules can generate corresponding feedback signals based on the feedback signal, so that the N-1 adjustment module connected to the N-1 feedback module adjusts the electrical signal in the voltage stabilizing circuit according to its input feedback signal, so that the voltage stabilizing circuit can output a stable electrical signal.

[0017] In one possible design, the voltage stabilizing circuit further includes a switching circuit; the output end of the i-th feedback module is connected to the input end of the i-th adjustment module, including: the output end of the i-th feedback module is connected to the input end of the i-th adjustment module through the switching circuit; the switching circuit is used to turn on M feedback modules out of N feedback modules; wherein M is less than or equal to N.

[0018] In this design, the switching circuit within the voltage regulator circuit allows it to switch between multiple operating modes. For example, in a radiation-exposed environment, when the switching circuit activates all feedback modules, the voltage regulator circuit operates in radiation-resistant mode. In this mode, all feedback modules work together to eliminate single-event effects caused by radiation exposure, allowing the voltage regulator circuit to output a stable electrical signal. Alternatively, in a radiation-free environment, when the switching circuit activates some feedback modules, the voltage regulator circuit operates in normal mode, reducing its energy consumption.

[0019] In one possible design, the voltage stabilizing circuit also includes a control circuit, wherein the input end of the control circuit is connected to the output end of the sensing module, and the output end of the control circuit is connected to the input end of the switching circuit; the control circuit is used to control the switching circuit to turn on M feedback modules out of N feedback modules according to the fluctuation value of the output electrical signal of the sensing module; wherein M is less than or equal to N.

[0020] In this design, the control circuit in the voltage-stabilizing circuit can control the switching circuit to adjust the operating mode of the voltage-stabilizing circuit based on the fluctuation value of the output electrical signal of the sensor module. The fluctuation value of the output electrical signal of the sensor module is related to the radiation environment; the stronger the radiation, the greater the fluctuation value. For example, when the fluctuation value of the output electrical signal of the sensor module is greater than a preset value, the control switching circuit can activate N feedback modules to enable the voltage-stabilizing circuit to operate in a radiation-resistant mode topology. Alternatively, when the fluctuation value of the output electrical signal of the sensor module is less than a preset value, the control switching circuit can activate some of the N feedback modules to enable the voltage-stabilizing circuit to operate in a normal mode topology. In this way, the operating mode can be automatically switched based on the radiation environment, thereby enabling the voltage-stabilizing circuit to strike a balance between radiation resistance and device power consumption.

[0021] In one possible design, the feedback module includes one or more differential amplifier circuits. In this design, the feedback module can be designed using one or more differential amplifier circuits, making the feedback module easy to implement and thus making the voltage stabilization circuit provided by the embodiment of the application easy to implement.

The output end of the entire module is connected to the input end of the sensing module; the method includes: the first adjustment module adjusts the input electrical signal of the voltage stabilizing circuit according to the first feedback signal, so that the voltage stabilizing circuit outputs the first electrical signal; the i-th adjustment module adjusts the output electrical signal of the i-1-th adjustment module according to the i-th feedback signal, so that the voltage stabilizing circuit outputs the i-th electrical signal; wherein the N-th electrical signal is the output electrical signal of the voltage stabilizing circuit; the sensing module collects the N-th first electrical signal and outputs N second electrical signals; the i-th reference signal module generates the i-th reference signal; the i-th feedback module generates the i-th feedback signal according to the i-th second electrical signal and the i-th reference signal, and inputs the j-th feedback signal into the i-th adjustment module.

[0023] In this method, a feedback module in a voltage stabilizing circuit can generate a corresponding feedback signal based on an electrical signal output by the voltage stabilizing circuit and a reference signal, and input the feedback signal into an adjustment module connected to the feedback module, so that the adjustment module can adjust the output electrical signal of its preceding adjustment module according to the feedback signal, so that the voltage stabilizing circuit can output a stable electrical signal.

[0052] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The specific operating methods in the method embodiments can also be applied to device embodiments or system embodiments. It should be noted that in the description of the present application, "at least one" refers to one or more, wherein "a plurality" refers to two or more. In view of this, "a plurality" can also be understood as "at least two" in the embodiments of the present application. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the previous and next associated objects are in an "or" relationship. In addition, it should be understood that in the description of the present application, words such as "first" and "second" are only used to distinguish the purpose of description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0053] In the embodiments of the present application, "connection" can be understood as electrical connection. The connection between two electrical components can be a direct or indirect connection between the two electrical components. For example, the connection between A and B can be either a direct connection between A and B or an indirect connection between A and B through one or more other electrical components. For example, the connection between A and B can also be a direct connection between A and C, and C and B can be directly connected, with A and B connected through C.

[0054] To facilitate understanding, the technical terms involved in the embodiments of this application are introduced below.

[0055] 1. Components usually refer to the smallest electronic components that realize basic functions, such as capacitors, resistors, inductors, transistors, and field-effect transistors.

[0056] 2. Devices can be understood as semiconductor components or electrical functional modules formed by arranging multiple semiconductor components. The devices involved in the embodiments of the present application include LDO power supplies.

[0057] 3. The space environment broadly refers to the Earth's mid- and upper atmosphere, ionosphere, magnetosphere, interplanetary space, and the solar atmosphere, which together constitute the terrestrial-solar environment. Spacecraft spend the vast majority of their operational life in the space environment. Statistics and research have shown that radiation in the space environment can cause single-event effects in electronic components within spacecraft, leading to malfunctions and compromising spacecraft reliability.

[0058] 4. Disturbance can be understood as fluctuations in the electrical signal (current or voltage) output by a circuit. The disturbances involved in the embodiments of this application include high-energy particles in the space environment acting on a component, causing the component to fail, which in turn causes fluctuations in the output electrical signal generated by the component or the circuit module composed of the component.

[0059] Figure 1 shows a schematic diagram of the structure of an LDO power supply. In Figure 1, the LDO power supply includes an adjustment module 101, a sensing module 102, a feedback module 103, and a reference signal module 104. The input electrical signal of the LDO power supply is an unadjusted, unstable voltage signal. After adjusting the input electrical signal, the LDO power supply can output a stable electrical signal. The adjustment module 101 is used to adjust the input electrical signal of the LDO power supply. The sensing module 102 is used to collect the electrical signal output by the adjustment module 101 and input the electrical signal into the feedback module 103. The reference signal module 104 can generate a reference signal and input it into the feedback module 103. The feedback module 103 can generate a feedback signal based on the electrical signal and the reference signal and input the feedback signal into the adjustment module 101. The adjustment module 101 then adjusts the input electrical signal of the LDO power supply based on the feedback signal, so that the LDO power supply outputs a stable electrical signal.

[0060] However, in a radiation environment, if any component in an LDO power supply experiences a single-particle effect (SPE), a feedback disturbance signal will be generated in the LDO power supply circuit. This feedback disturbance signal can cause fluctuations in the stable electrical signal output by the LDO power supply. For example, in Figure 2, the LDO power supply can stably output a 5V voltage signal when no SPE occurs. However, when a SPE occurs, the voltage signal output by the LDO power supply fluctuates between 5.5V and 7V, potentially causing downstream components connected to the LDO power supply to operate abnormally due to voltage fluctuations. Alternatively, as shown in Figure 3, the LDO power supply can stably output a 5V voltage signal when no SPE occurs. However, when a SPE occurs, the voltage signal output by the LDO power supply is around 0.35V, potentially causing downstream components connected to the LDO power supply to operate abnormally due to low voltage.

[0061] As shown in Figure 4A, some technical solutions improve the stability of the LDO power supply's output voltage by designing a capacitor connected to the LDO power supply in the circuit to filter the voltage signal output by the LDO power supply to eliminate feedback disturbance signals caused by single-particle effects. However, the filtering effect in this solution is related to the size of the capacitor. For feedback disturbance signals with long duration and large amplitude, a larger capacitor is required for filtering, which will reduce the response speed of the LDO power supply and affect its performance.

[0062] Other technical solutions connect multiple LDO power supplies in parallel, and incorporate a comparison system into the circuit to compare the power supply conditions of these multiple LDO power supplies. Based on the comparison results, the system filters out output signals with significant fluctuations. As shown in Figure 4B, when three LDO power supplies are connected in parallel, the comparison system compares the output electrical signals of the three LDO power supplies and disables the output signals of any LDO power supply experiencing fluctuations due to single-event effects. This prevents downstream components connected to the LDO power supplies from being affected by the fluctuating voltage signals and causing malfunctions. However, this solution involves significant circuit overhead, which increases the hardware cost of the LDO power supplies.

[0063] As shown in Figure 4C, in some other technical solutions, a digital control circuit is provided within the LDO power supply circuit. This digital control circuit monitors the electrical signal output by the LDO power supply. When the LDO power supply experiences a single-event effect, causing the output electrical signal to fluctuate, the digital control circuit can generate a digital signal that can provide feedback and adjust the output electrical signal of the LDO power supply to ensure a stable output electrical signal. However, the digital control circuit itself can also experience single-event effects, which can cause the LDO power supply to fail.

[0064] Other technical solutions employ a large number of specialized radiation-hardened components to manufacture LDO power supplies, thereby improving their radiation resistance. However, the high cost of these components leads to higher manufacturing costs for LDO power supplies. Furthermore, due to the limitations of the process lines used for these components, LDO power supplies manufactured with these components often exhibit poor performance.

[0065] In summary, in radiation environments, components in LDO power supplies can experience single-event effects, leading to significant fluctuations in the voltage signal output by the LDO power supply. However, current LDO power supply radiation-resistant solutions are either expensive or offer poor performance. Therefore, cost-effectively improving the radiation resistance and reliability of LDO power supplies, ensuring a stable voltage output, is a pressing technical challenge.

[0066] In view of this, an embodiment of the present application provides a voltage-stabilizing circuit for improving the stability of the electrical signal output by a power supply device or power supply component. The output ends of the N feedback modules in the voltage-stabilizing circuit provided in the embodiment of the present application are connected one-to-one to the input ends of the N adjustment modules. Therefore, when the components in the voltage-stabilizing circuit produce a single-particle effect in a radiation environment, the N adjustment modules can adjust the electrical signal in the voltage-stabilizing circuit according to the feedback signals output by the N feedback modules, thereby eliminating fluctuations in the electrical signal output by the voltage-stabilizing circuit due to the single-particle effect, allowing the voltage-stabilizing circuit to output a stable electrical signal. In this way, the radiation resistance of the voltage-stabilizing circuit is effectively improved, thereby improving the reliability of the voltage-stabilizing circuit.

[0067] The voltage stabilizing circuit provided in the embodiment of the present application can be arranged in a power supply device (such as an LDO power supply in a spacecraft), thereby effectively improving the stability of the output voltage of the power supply device, thereby improving the working stability of the powered device or the powered component. Among them, the LDO power supply can be used as a tertiary power supply to power the subsequent components in a variety of scenarios. For example, the LDO power supply can be arranged in the digital circuit part of a satellite communication payload or a satellite control system, and then the LDO power supply can be used as a tertiary power supply to provide a stable voltage for IC chips, clocks, control circuits, etc. For another example, the LDO power supply can be arranged in the analog circuit part of a satellite communication payload or a satellite control system as a tertiary power supply to provide a stable voltage for the driving power supply. For another example, the LDO power supply can be used as a tertiary power supply in facilities and equipment with radiation environments such as industry.

[0068] The following will introduce the system architecture involved in the embodiments of the present application with reference to specific drawings.

[0069] FIG5A shows one of the structural diagrams of a voltage stabilizing circuit provided by an embodiment of the present application. In FIG5A , the voltage stabilizing circuit 500 includes a sensing module 501, a feedback module 1-feedback module N, a reference signal module 1-reference signal module N, and an adjustment module 1-adjustment module N; wherein, the adjustment module 1-adjustment module N are connected in series, the input end of the adjustment module 1 is the input end of the voltage stabilizing circuit 500, and the output end of the adjustment module N is the output end of the voltage stabilizing circuit 500; the output end of the adjustment module N is connected to the input end of the sensing module 501; the input end of the feedback module 1 is respectively connected to the output end of the reference signal module 1 and the output end of the sensing module 501, and the output end of the feedback module 1 is connected to the input end of the adjustment module 1; the input end of the feedback module i is respectively connected to the output end of the reference signal module i and the output end of the sensing module 501, and the output end of the feedback module i is connected to the input end of the adjustment module i; ..., and so on, the input end of the feedback module N is connected to the output end of the sensing module 501, and the output end of the feedback module N is connected to the input end of the adjustment module N.

[0070] The first adjustment module in the voltage stabilizing circuit 500 can adjust the input electrical signal of the voltage stabilizing circuit according to the first feedback signal and output the first electrical signal; the i-th adjustment module in the voltage stabilizing circuit 500 can adjust the i-1-th electrical signal according to the i-th feedback signal and output the i-th electrical signal; ..., and so on, the N-th adjustment module in the voltage stabilizing circuit 500 can adjust the N-1-th electrical signal according to the N-th feedback signal and output the N-th electrical signal; wherein i is a positive integer greater than 1 and less than N. The N-th electrical signal is the output electrical signal of the voltage stabilizing circuit; the sensing module 501 can collect the N-th first electrical signal and output N second electrical signals, which are respectively input into feedback module 1 to feedback module N; the i-th feedback module among the N feedback modules can generate the i-th feedback signal according to the i-th second electrical signal and the i-th reference signal, and the i-th feedback signal is input into the i-th adjustment module. In this way, the feedback module can generate a corresponding feedback signal based on the electrical signal output by the voltage stabilizing circuit and the reference signal, and input the feedback signal into the adjustment module connected to the feedback module, so that the adjustment module can adjust the output electrical signal of its preceding adjustment module according to the feedback signal, so that the voltage stabilizing circuit can output a stable electrical signal.

[0071] Reference signal modules 1 through N may comprise one or more modules (see FIG5A for example). For example, a reference signal module may be provided in the voltage stabilization circuit 500, which may generate N reference signals and provide these N reference signals to feedback modules 1 through N, respectively. For another example, N reference signal modules may be provided in the voltage stabilization circuit 500, each of which may generate one reference signal and provide a reference signal to one feedback module. These N reference signals may be the same or different.

[0072] Similarly, the sensing module 501 can be one or more modules. For example, a sensing module can be provided in the voltage stabilizing circuit 500. In another example, N sensing modules can be provided in the voltage stabilizing circuit 500, and each sensing module can collect an electrical signal output by the voltage stabilizing circuit 500 and input it into the feedback module connected thereto. In this way, if a sensing module is damaged, the other sensing modules can still continue to collect the electrical signal output by the voltage stabilizing circuit 500, allowing the voltage stabilizing circuit 500 to operate normally, thereby effectively improving the reliability of the voltage stabilizing circuit 500.

[0073] As shown in FIG5B , when a single-particle effect occurs in the voltage stabilizing circuit 500, the feedback signal 1 output by the feedback module N is affected by the single-particle effect and generates a feedback disturbance signal. The feedback disturbance signal fluctuates, and the feedback disturbance signal is input into the adjustment module N. The electrical signal output by the adjustment module N fluctuates. Furthermore, the electrical signal output by the adjustment module N collected by the sensing module 501 also fluctuates. The electrical signal output by the adjustment module N is input into the feedback module 1 and the feedback module 2 respectively. The reference signal module 1 generates a reference signal 1 and inputs the reference signal 1 into the feedback module 1. The reference signal module 2 generates a reference signal 1. The sensor module 501 generates a reference signal 2 and inputs the reference signal 2 into the feedback module 2. The feedback module 1 generates a feedback signal 1 based on the electrical signal output by the sensor module 501 and the reference signal 1. The feedback signal 1 is input into the adjustment module 1, and the adjustment module 1 adjusts the input electrical signal of the voltage stabilizing circuit 500. The feedback module 2 generates a feedback signal 2 based on the electrical signal output by the sensor module 501 and the reference signal 2. The feedback signal 2 is input into the adjustment module 2, and the adjustment module 2 adjusts the input electrical signal of the voltage stabilizing circuit 500 so that the fluctuation value of the electrical signal output by the adjustment module 2 is less than a preset value. In this way, the radiation resistance of the voltage stabilizing circuit 500 can be improved, the voltage stabilizing circuit 500 outputs a stable voltage signal, and the reliability of the voltage stabilizing circuit 500 can be improved.

[0074] FIG5C shows a third structural schematic diagram of a voltage stabilizing circuit provided by an embodiment of the present application. In FIG5C , the voltage stabilizing circuit 500 further includes a switch circuit 502; wherein the output end of feedback module 1 is connected to the input end of adjustment module 1 via the switch circuit 502, the output end of feedback module 2 is connected to the input end of adjustment module 2 via the switch circuit 502, ..., and so on, the output end of feedback module N is connected to the input end of adjustment module N via the switch circuit 502; accordingly, the switch circuit 502 can control the activation of M feedback modules out of N feedback modules; wherein M is less than or equal to N. In this way, the switch circuit 502 can control the activation of M feedback modules out of N feedback modules, and can change the circuit topology of the voltage stabilizing circuit 500, so that the voltage stabilizing circuit 500 can switch between multiple operating modes. For example, in a radiation environment, when the switch circuit 502 activates all feedback modules, the voltage stabilizing circuit 500 is in an anti-radiation mode. At this time, all feedback modules work together to eliminate single event effects caused by the radiation environment, so that the voltage stabilizing circuit 500 can output a stable electrical signal. For another example, in an environment without radiation, when the switch circuit 502 activates part of the feedback module, the voltage stabilizing circuit 500 is in a normal mode, and the energy consumption of the voltage stabilizing circuit 500 can be reduced.

[0075] In an embodiment of the present application, in one case, the switch circuit 502 is set between N feedback modules and N adjustment modules, and can serve as the enable control terminal of the N feedback modules and the N adjustment modules; in another case, the switch circuit 502 is connected to the enable terminals of the N feedback modules and the N adjustment modules, and is used to control the enablement of the N feedback modules and the N adjustment modules.

[0076] FIG5D shows a third schematic diagram of the structure of a voltage stabilizing circuit provided in an embodiment of the present application. In FIG5D , the voltage stabilizing circuit 500 further includes a control circuit 503, the output end of the control circuit 503 being connected to the output end of the sensor module 501, and the output end of the control circuit 503 being connected to the input end of the switch circuit 502; and the control circuit 503 can control the switch circuit 502 to activate M feedback modules out of N feedback modules according to the fluctuation value of the output electrical signal of the sensor module 501. In this way, the control circuit 503 in the voltage stabilizing circuit 500 can control the switch circuit 502 to adjust the operating mode of the voltage stabilizing circuit 500 according to the fluctuation value of the output electrical signal of the sensor module.

[0077] The fluctuation value of the output electrical signal of the sensor module 501 is related to the radiation environment; the stronger the radiation, the greater the fluctuation value. For example, when the fluctuation value of the output electrical signal of the sensor module is greater than a preset value, the control switch circuit 502 activates N feedback modules to enable the voltage regulator circuit 500 to operate in the radiation-resistant mode topology. For another example, when the fluctuation value of the output electrical signal of the sensor module is less than a preset value, the control switch circuit 502 activates some of the N feedback modules to enable the voltage regulator circuit 500 to operate in the normal mode topology. In this way, the operating mode can be automatically switched based on the radiation environment, thereby ensuring that the voltage regulator circuit 500 achieves a balance between radiation resistance and device power consumption.

[0094] For ease of understanding, the voltage stabilizing circuit 500 is further introduced below with reference to a specific structural example diagram of the voltage stabilizing circuit 500 .

[0095] For example, FIG5G shows a fourth structural diagram of a voltage stabilizing circuit provided in an embodiment of the present application. In FIG5F, the voltage stabilizing circuit 500 includes an adjustment module 1, an adjustment module 2, a feedback module 1, a feedback module 2, a reference signal module 1, a reference signal module 2, and a sensor module 501; wherein, the adjustment module 1 and the adjustment module 2 are both PMOS tubes, the input end of the adjustment module 1 is the input end V_IN of the voltage stabilizing circuit 500, and the output end of the adjustment module 2 is the output end V_OUT of the voltage stabilizing circuit 500; the sensor module 501 includes a resistor R1 and a resistor R2, one end of the resistor R1 is connected to the output end V_OUT of the voltage stabilizing circuit 500, and the resistor R1 is connected to the output end V_OUT of the voltage stabilizing circuit 500.

One input end of the differential amplifier circuit 1 and the differential amplifier circuit 2 are respectively connected to the intermediate node between the resistor R1 and the resistor R2, the other input end of the differential amplifier circuit 1 is connected to the reference signal module 1, and the other input end of the differential amplifier circuit 2 is connected to the reference signal module 2. The output end of the differential amplifier circuit 1 is connected to the input end of the adjustment module 1, and the output end of the differential amplifier circuit 2 is connected to the input end of the adjustment module 2. Optionally, the voltage stabilizing circuit 500 may further include a capacitor C1, one end of the capacitor C1 is connected to the output end V_OUT of the voltage stabilizing circuit 500, and the other end of the capacitor C1 is grounded. The capacitor C1 is used to filter the electrical signal output by the voltage stabilizing circuit 500.

[0096] As shown in FIG5H , the voltage stabilizing circuit 500 further includes a switch circuit 502, which is connected to the adjustment module 1, the adjustment module 2, and the feedback module 1, and the feedback module 2, respectively. Thus, the switch circuit 502 can control the enable terminals of the adjustment module 1, the adjustment module 2, the feedback module 1, and the feedback module 2. Optionally, the switch circuit 502 can also be connected to the input terminal V_IN of the voltage stabilizing circuit 500 to control the enable signal of the voltage stabilizing circuit 500.

[0097] As shown in Figure 5I, the voltage stabilizing circuit 500 also includes a control circuit 503, the input end of the control circuit 503 is connected to the intermediate node between the resistor R1 and the resistor R2, so that the control circuit 503 can monitor the electrical signal output by the voltage stabilizing circuit 500; the output end of the control circuit 503 is connected to the input end of the switching circuit 502, so that the control circuit 503 can start the feedback module 1 and / or feedback module 2 according to the fluctuation value of the electrical signal output by the voltage stabilizing circuit 500, thereby realizing the switching of the working topology structure of the voltage stabilizing circuit 500.

[0098] In some examples of the present application, the N adjustment modules in the voltage stabilizing circuit 500 can have multiple connection modes, such as multiple adjustment modules connected in series. For example, Figure 6 shows a fourth structural schematic diagram of a voltage stabilizing circuit provided by an embodiment of the present application. In Figure 7, the voltage stabilizing circuit 500 includes a sensing module 501, a feedback module 1-feedback module 2, and an adjustment module 1-adjustment module 4; wherein, the adjustment module 1 and the adjustment module 2 are connected in series, the adjustment module 3 and the adjustment module 4 are connected in series, the circuit in which the adjustment module 1 and the adjustment module 2 are connected in series is connected in parallel with the circuit in which the adjustment module 3 and the adjustment module 4 are connected in series, the input end of the adjustment module 4 and the output end of the adjustment module 2 are connected in parallel to form the output end of the voltage stabilizing circuit 500, and the output end of the voltage stabilizing circuit 500 is connected to the input end of the sensing module 501; the output end of the sensing module 501 is connected to the input end of the feedback module 1 and the feedback module 2 respectively, the output end of the feedback module 1 is connected to the input end of the adjustment module 3 and the adjustment module 4, and the output end of the feedback module 2 is connected to the input end of the adjustment module 1 and the adjustment module 2.

[0099] Among them, when the voltage stabilizing circuit 500 is in a radiation environment and a single particle effect occurs, the feedback module 2 generates a feedback disturbance signal due to the single particle effect, and inputs the feedback disturbance signal into the adjustment module 1 and the adjustment module 2 respectively. The adjustment module 1 and the adjustment module 2 adjust the input electrical signal of the voltage stabilizing circuit 500 based on the feedback disturbance signal, so that the output electrical signal of the voltage stabilizing circuit 500 will fluctuate; at this time, the sensor module 501 collects the output electrical signal of the voltage stabilizing circuit 500, and the sensor module 501 inputs the electrical signal to the feedback module 1. The feedback module 1 generates a feedback signal based on the reference signal 1 generated by the reference signal module 1 and the electrical signal, and the feedback signal is input into the adjustment module 3 and the adjustment module 4 respectively; the adjustment module 3 and the adjustment module 4 adjust the input electrical signal of the voltage stabilizing circuit 500 based on the feedback signal; in this way, the fluctuation of the output electrical signal of the voltage stabilizing circuit 500 caused by the feedback disturbance signal can be eliminated, so that the voltage stabilizing circuit 500 can output a stable electrical signal.

[0100] In FIG6 , by connecting multiple adjustment modules in parallel, the driving capability of the voltage stabilizing circuit can be improved and the voltage adjustment capability of the voltage stabilizing circuit can be enhanced.

[0101] Based on the above content and the same concept, an embodiment of the present application provides an adjustment method, which is applicable to a voltage stabilizing circuit 500. The voltage stabilizing circuit 500 includes a sensing module 501, N reference signal modules, N feedback modules, and N adjustment modules; wherein the N feedback modules are respectively the first feedback module to the Nth feedback module, and the N adjustment modules are respectively the first adjustment module to the Nth adjustment module; N is an integer greater than 2, and i is an integer greater than or equal to 2 and less than N. As shown in Figure 7, the adjustment method includes:

[0102] S701: A first adjustment module in the voltage stabilizing circuit 500 adjusts an input electrical signal of the voltage stabilizing circuit 500 according to a first feedback signal, so that the adjustment module outputs a first electrical signal.

[0103] S702. The i-th adjustment module in the voltage stabilizing circuit 500 adjusts the output electrical signal of the i-1-th adjustment module according to the i-th feedback signal, so that the adjustment module outputs the i-th electrical signal; wherein the N-th first electrical signal is the output electrical signal of the voltage stabilizing circuit.

[0104] S703: The sensing module 501 collects the Nth first electrical signal and outputs N second electrical signals.

[0105] S704 , N reference signal modules generate an i th reference signal.

[0106] S705 , the i th feedback module in the voltage stabilizing circuit 500 generates an i th feedback signal according to the i th second electrical signal and the i th reference signal, and the i th feedback signal is input into the i th adjustment module.

[0107] In the specific implementation of S704, when the j-th feedback signal fluctuates, the feedback modules other than the j-th feedback module among the N feedback modules generate N-1 feedback signals based on the j-th feedback signal, and the N-1 feedback signals are respectively input into the N-1 adjustment modules other than the j-th adjustment module among the N adjustment modules; wherein, one feedback module corresponds to one feedback signal, and one feedback signal corresponds to one adjustment module; the output electrical signal of the N-1 adjustment module is adjusted based on the N-1 feedback signals by the adjustment modules other than the j-th adjustment module among the N adjustment modules to reduce the fluctuation value of the output electrical signal of the voltage stabilizing circuit.

[0108] For example, please continue to refer to Figure 5G. The feedback module 1 in the voltage stabilizing circuit 500 is a differential amplifier circuit 1, and the feedback module 2 in the voltage stabilizing circuit 500 is a differential amplifier circuit 2. When the voltage stabilizing circuit 500 produces a single particle effect, the feedback signal 1 output by the differential amplifier circuit 1 is affected by the single particle effect to generate a feedback disturbance signal. The feedback disturbance signal fluctuates. The feedback disturbance signal is input to the adjustment module 1, and the electrical signal output by the adjustment module 1 fluctuates. Then, the electrical signal output by the adjustment module 2 collected by the sensor module 501 also fluctuates. The adjustment module The electrical signals output by adjustment module 2 are input into differential amplifier circuit 1 and differential amplifier circuit 2, respectively. Reference signal module 1 generates reference signal 1 and inputs reference signal 1 into differential amplifier circuit 1. Reference signal module 2 generates reference signal 2 and inputs reference signal 2 into differential amplifier circuit 2. Differential amplifier circuit 2 generates feedback signal 2 based on the electrical signal output by adjustment module 2 and reference signal 1. Feedback signal 2 is input into adjustment module 1, which then adjusts the input electrical signal of voltage stabilization circuit 500 so that the fluctuation value of the electrical signal output by adjustment module 2 is less than a preset value. This improves the radiation resistance of voltage stabilization circuit 500, enables voltage stabilization circuit 500 to output a stable voltage signal, and enhances the reliability of voltage stabilization circuit 500. As shown in (a) of FIG8 , when a single-particle effect occurs in the voltage-stabilizing circuit 500, the voltage-stabilizing circuit 500 is affected by the feedback disturbance signal formed by the single-particle effect. If the electrical signal output by the voltage-stabilizing circuit 500 is not adjusted, the electrical signal output by the voltage-stabilizing circuit 500 has a large fluctuation value. As shown in (b) of FIG8 , when a single-particle effect occurs in the voltage-stabilizing circuit 500, although the voltage-stabilizing circuit 500 is affected by the feedback disturbance signal formed by the single-particle effect, after the adjustment module and the feedback module in the voltage-stabilizing circuit 500 adjust the electrical signal output by the voltage-stabilizing circuit 500, the fluctuation value of the electrical signal output by the voltage-stabilizing circuit 500 is small.
