DETAILED DESCRIPTION

[0030] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0031] With the evolution of RF technology, higher requirements are also put forward for RF devices. For example, in order to meet the requirements of SCS 30KHz and 60KHz, the voltage switching speed of RF PMIC needs to be extremely fast, within 5uS, which leads to voltage overcharging. This overcharge voltage may cause breakdown and damage to the power amplifier, making it unable to work.

[0032] In the related art, in order to avoid damage to the power amplifier, the power amplifier is turned off when the input voltage is greater than the operating voltage. However, this will cause the power amplifier to have no uplink signal, resulting in a decrease in uplink throughput or failure to communicate normally.

[0033] Based on the above technical problems, the present application provides an electronic device 1, such as Figure 1 As shown, the electronic device 1 includes:

[0034] The power supply module 11 includes a power supply terminal;

[0035] A control module, the control module may have a control input terminal and a control output terminal, the control input terminal may be electrically connected to the power supply terminal, and the control module may be used to output a control signal according to an electrical signal from the power supply terminal;

[0036] The impedance adjustment module 13 may include a first electrical input terminal, a first electrical output terminal and a controlled terminal, wherein the first electrical input terminal may be electrically connected to the power supply terminal, the controlled terminal may be electrically connected to the control output terminal, and the impedance adjustment module 13 may be used to change its own impedance according to a control signal output by the control output terminal;

[0037] a target circuit module 14, wherein the target circuit module 14 may have a second electrical input terminal, wherein the second electrical input terminal may be electrically connected to the first electrical output terminal of the impedance adjustment module 13, and the target circuit module 14 may have a target withstand power;

[0038] The power of the electrical signal outputted by the first electrical output terminal of the impedance adjustment module 13 is less than or equal to the target withstand power.

[0039] In this embodiment, the power supply module can be used to supply power to the electronic device, so as to transmit the electrical signal to the electronic device, and the electronic device operates through the electrical signal transmitted by the power supply module. The power supply module can be a power supply, a power supply, or other devices for supplying power.

[0040] In this embodiment, the control module can be used to output a control signal according to the electrical signal received from the power supply module. The control module can be a controller, MCU, comparator, resistance module, or other device that can realize signal control or conversion.

[0041] In this embodiment, the impedance adjustment module is a device that can adjust the magnitude of an electrical signal, and can be a circuit module with a certain impedance, such as a combination of resistors or other impedance elements.

[0042] In this embodiment, the target circuit module is a device that can realize the function of the electronic device, and can be a radio frequency device, a display device, or other devices that can realize the function.

[0043] An electronic device 1 provided in an embodiment of the present application may include a power supply module 11, a control module, an impedance adjustment module 13 and a target circuit module 14. The power supply module 11 may be used for power supply. The control input terminal of the control module is connected to the power supply module 11 to receive an electrical signal transmitted by the power supply module 11. The control module may output a control signal through a control output terminal according to the electrical signal. The impedance adjustment module 13 may include a first electrical input terminal, a first electrical output terminal and a controlled terminal. The first electrical input terminal is connected to the power supply terminal to receive an electrical signal from the power supply module 11. The controlled terminal is connected to the control output terminal of the control module to receive a control signal output by the control module according to the electrical signal of the power supply module 11. The impedance adjustment module 13 may output a control signal according to the electrical signal of the power supply module 11 through a control output terminal. The control signal sent by the control module changes its own impedance, so that the output voltage signal can be adjusted by changing its own impedance. The first electrical output end of the impedance adjustment module 13 can be connected to the target circuit module 14 to transmit the voltage signal adjusted by the impedance adjustment module 13 to the target circuit module 14, and the power of the electrical signal output by the first electrical output end of the impedance adjustment module 13 is less than or equal to the target tolerance power of the target circuit module 14. Therefore, after the electrical signal adjusted by the blocking adjustment module is transmitted to the target circuit module 14, its power is the power that the target circuit module 14 can withstand, thereby avoiding breakdown and damage to the target circuit module 14 due to excessively high received voltage.

[0044] Therefore, the electronic device 1 provided in the present application may not shut down the target circuit module 14 when the voltage signal output by the power supply module 11 is too large. Instead, the control module controls the impedance of the impedance adjustment module 13 to adjust its own impedance to change the voltage signal input to the target circuit module 14, so that the power of the voltage signal received by the target circuit module 14 is less than or equal to the target tolerance power of the target circuit module 14, thereby protecting the target circuit module 14 and improving performance and user experience.

[0045] In an embodiment of the present application, the power of the electrical signal output by the power supply end is greater than the target tolerance power.

[0046] In this embodiment, the power supply end can be connected to the control module and the impedance adjustment module 13, and the electrical signal is transmitted to the control module and the impedance adjustment module 13, and then transmitted to the target circuit module 14 after adjustment by the impedance adjustment module 13. In the case where the electrical signal output by the power supply end is greater than the target withstand power of the target circuit module 14, the control module can output a control signal to the impedance adjustment module 13 according to the received electrical signal, and the impedance adjustment module 13 can adjust its own impedance according to the control signal to adjust the power of the electrical signal sent by the power supply module 11 received by the impedance adjustment module 13, so that the power of the electrical signal output by the impedance adjustment module 13 is less than or equal to the target withstand power of the target circuit module 14, so that the target circuit module 14 can move normally and avoid being damaged by the power of the electrical signal output by the power supply module 11 that is greater than the target withstand power, thereby protecting the target circuit module 14.

[0047] In another embodiment of the present application, the electrical signal output by the power supply end is less than or equal to the target tolerance power of the target circuit module 14, and the control module can output a control signal to the impedance adjustment module 13 based on the received electrical signal, so that the impedance adjustment module 13 can adjust its own impedance according to the control signal, so that the impedance of the impedance adjustment module 13 itself is approximately 0, so that the power of the electrical signal sent by the power supply module 11 received by the impedance adjustment module 13 is not adjusted, and then the impedance adjustment module 13 transmits the electrical signal output by the power supply module 11 to the target circuit module 14, and the target circuit module 14 can operate normally.

[0048] In the embodiments of the present application, Figure 2 As shown, the impedance adjustment module 13 may include a switch unit 131 and a plurality of impedance adjustment branches with different impedances.

[0049] The output end of the impedance adjustment branch can be constructed as the first electrical output end of the impedance adjustment module 13.

[0050] The input end of the switch unit 131 can be constructed as a controlled end of the impedance adjustment module 13, the output end of the switch unit 131 can be connected to a plurality of impedance adjustment branches, and the switch unit 131 is used to be turned on or off according to the electrical signal output by the control output end.

[0051] In this embodiment, the input end of the switch unit 131 can be constructed as a controlled end of the impedance adjustment module 13, so as to receive the control signal sent by the control module. The output end of the switch unit 131 can be connected to multiple impedance adjustment branches. The switch unit 131 can control the conduction or cutoff of the electrical signal at the output end according to the received control signal, that is, one or more different impedance adjustment branches can be controlled to be turned on according to the received control signal, while the remaining impedance adjustment branches are cut off. The one or more different impedance adjustment branches that are turned on form the resistance of the impedance adjustment module 13, so as to achieve the adjustment of the impedance of the impedance adjustment module 13 itself. Furthermore, the input end of the switch unit 131 can also be constructed as a first electrical input end, which can be used to receive the electrical signal transmitted by the power supply module 11. The switch unit 131 can transmit the received electrical signal to one or more impedance adjustment branches that are turned on. After the impedance is adjusted by one or more impedance adjustment branches, the electrical signal output from the impedance adjustment branch is changed compared with the electrical signal output from the power supply module 11. The power of the electrical signal output by the power supply module 11 is greater than the target tolerance power of the target circuit module 14, while the power of the electrical signal after impedance adjustment by one or more impedance adjustment branches is less than or equal to the target tolerance power of the target circuit module 14, so that the circuit module can move normally and avoid damage.

[0052] like Figure 2 As shown, in an embodiment of the present application, the multiple impedance adjustment branches may include at least a first impedance adjustment branch 132 and a second impedance adjustment branch 133, the first impedance adjustment branch 132 may be provided with an impedance element, and the second impedance adjustment branch 133 may not be provided with an element with impedance.

[0053] In one embodiment of the present application, when the electrical signal output from the power supply end is greater than the target withstand power of the target circuit module 14, the control module can output an impedance adjustment signal to the switch unit 131 according to the received electrical signal, so that the switch unit 131 controls the first impedance adjustment branch 132 to be in a conducting state, and can control the second impedance adjustment branch 133 to be in a truncated state, so that the impedance adjustment module 13's own resistance is the resistance element on the first impedance adjustment branch 132, so that the resistance element can perform impedance adjustment for the electrical signal sent by the power supply module 11 received by the impedance adjustment module 13, so as to reduce the power of the electrical signal, so that the power of the electrical signal is small. The target withstand power of the target circuit module 14 is equal to or less than the target withstand power of the target circuit module 14, that is, the electrical signal transmitted by the power supply module 11 can be transmitted to the target circuit control module through the output end of the first impedance adjustment branch 132. During the transmission process, the impedance of the impedance element on the first impedance adjustment branch 132 is adjusted so that the power of the electrical signal is less than or equal to the target withstand power of the target circuit module 14, so that the power of the electrical signal received by the target circuit module 14 is less than the target withstand power, and the target circuit module 14 can operate normally to avoid being damaged by the power of the electrical signal output by the power supply module 11 which is greater than the target withstand power, thereby protecting the target circuit module 14.

[0054] In another embodiment of the present application, the electrical signal output by the power supply end may be less than or equal to the target withstand power of the target circuit module 14, and the control module may output a non-impedance adjustment signal to the impedance adjustment module 13 based on the received electrical signal, so that the switch unit 131 controls the second impedance adjustment branch 133 to be in an on state, and may control the first impedance adjustment branch 132 to be in an off state, and the second impedance adjustment branch 133 is a transmission line, so that the impedance adjustment module 13 has its own resistance approximately 0, so that the impedance adjustment module 13 may not perform impedance adjustment on the electrical signal received from the power supply module 11, that is, the electrical signal transmitted by the power supply module 11 is transmitted through the second impedance adjustment branch 133, and is transmitted from the output end of the second impedance adjustment branch 133 to the target circuit module 14, and the target circuit module 14 may operate normally.

[0055] In this embodiment, there may be multiple impedance adjustment branches, and the impedances on the impedance adjustment branches may be the same or different. Impedance adjustment branches with the same or different impedances may be connected to the switch unit 131 and the target circuit module 14 individually. Alternatively, multiple impedance adjustment branches may be used as a whole to adjust the impedance of the electrical signal, and after adjustment, they may be connected to the target circuit module 14 using a summary line.

[0056] like Figure 2As shown, in the embodiment of the present application, the switch unit 131 may be a single-pole multi-throw switch, which may be used to connect one of the impedance adjustment branches according to the electrical signal output from the control output terminal.

[0057] In one embodiment, the impedance adjustment module 13 may include a switch unit 131 and a plurality of impedance adjustment branches with different impedances. The input end of the switch unit 131 is connected to the power supply module 11 so as to receive the electrical signal transmitted by the power supply module 11, and the input end of the switch unit 131 may also be connected to the control module to receive the control signal sent by the control module. When the power of the electrical signal sent by the power supply module 11 is greater than the target tolerance power of the target circuit module 14, the control signal sent by the control module to the switch unit 131 is an impedance adjustment signal. After receiving the impedance adjustment signal, the output end of the switch unit 131 may be connected to one or more impedance adjustment branches having resistance elements so that the electrical signal is transmitted through the one or more impedance adjustment branches having resistance elements. The impedance of the electrical signal is adjusted during the transmission process so that the power of the electrical signal output from the first electrical output end of the impedance adjustment module 13 is less than the target tolerance power, and the electrical signal with a power less than the target tolerance power is transmitted to the target circuit module 14, so that the target circuit module 14 can operate normally.

[0058] In another embodiment, when the power of the electrical signal sent by the power supply module 11 is less than or equal to the target tolerance power of the target circuit module 14, the control signal sent by the control module to the switch unit 131 is a non-impedance adjustment signal. After receiving the non-impedance adjustment signal, the output end of the switch unit 131 can be connected to an impedance adjustment branch without an impedance element, so that the electrical signal is transmitted through the impedance adjustment branch without a resistance element, and the power of the electrical signal will not be lost during the transmission process. Then, the electrical signal with a power less than the target tolerance power is transmitted to the target circuit module 14, so that the target circuit module 14 can operate normally.

[0059] like Figure 2 As shown, in an embodiment of the present application, the control module may include a comparator 121, and the comparator 121 may have a first end, a second end, and a third end. The first end may be used to receive a comparison voltage electrical signal, the second end of the comparator 121 may be constructed as a control input end of the control module, and the third end of the comparator 121 may be constructed as a control output end of the control module.

[0060] In this embodiment, the second end of the comparator 121 can be a control input end, which is used to receive the electrical signal sent by the power supply module 11. The first end of the comparator 121 can be connected to the comparison voltage module 15, which is used to receive the comparison voltage signal sent by the comparison voltage module 15. The comparator 121 can be used to compare the electrical signal sent by the power supply module 11 with the comparison voltage signal. The power of the comparison voltage signal is equal to the target withstand power of the target circuit module 14. Therefore, when the power of the electrical signal sent by the power supply module 11 is greater than the power of the comparison voltage signal, the comparator 121 can send an impedance adjustment signal to the impedance adjustment module 13, so that the electrical signal of the power supply module 11 can pass through the impedance adjustment module 13 having an impedance element. The impedance adjustment branch adjusts the impedance of the electrical signal so that the power of the electrical signal output from the impedance adjustment module 13 to the target circuit module 14 is less than or equal to the target tolerance power, so that the target circuit module 14 can operate normally; and when the power of the electrical signal sent by the power supply module 11 is less than or equal to the power of the comparison voltage signal, the comparator 121 can send a non-impedance adjustment signal to the impedance adjustment module 13, so that the electrical signal of the power supply module 11 can pass through the impedance adjustment module 13 without adjusting the size of the electrical signal through the impedance adjustment module 13, and the impedance adjustment module 13 can transmit the electrical signal to the target circuit module 14 through the impedance adjustment branch without setting an impedance element, so that the target circuit module 14 can operate normally.

[0061] like Figure 2 As shown, in the embodiment of the present application, it also includes: a comparison voltage module 15, which may include a comparison voltage supply terminal connected to the first terminal of the comparator 121, and can be used to supply a comparison voltage electrical signal to the first terminal of the comparator 121.

[0062] In this embodiment, the electronic device 1 may include a comparison voltage module 15, a power supply module 11, a comparator 121, an impedance adjustment module 13 and a target circuit module 14. The comparison voltage module 15 may have a comparison voltage supply terminal, and the impedance voltage supply terminal may be used to connect with the comparator 121 to transmit the comparison voltage electrical signal to the comparator 121. The comparator 121 may also be connected with the power supply module 11 to receive the electrical signal sent by the power supply module 11. The comparator 121 may be used to compare the comparison voltage electrical signal with the electrical signal transmitted by the power supply module 11. If the power of the comparison voltage electrical signal is greater than the power supply, the comparison voltage electrical signal is transmitted to the comparator 121. The power of the electrical signal transmitted by the module 11, the comparator 121 can send an impedance adjustment signal to the switch unit 131 of the impedance adjustment module 13, and the impedance adjustment signal can be a high-level signal. Then the switch unit 131 can be connected to the first impedance adjustment branch 132 having an impedance element according to the high-level signal, and the input end of the switch unit 131 can also be connected to the power supply module 11 to receive the electrical signal. After the switch unit 131 is connected to the first impedance adjustment branch 132, the switch unit 131 transmits the electrical signal to the first impedance adjustment branch 132. The impedance element on the first impedance adjustment branch 132 can be The electrical signal is impedance-adjusted so that the power of the electrical signal output from the output end of the first impedance adjustment branch 132 is less than or equal to the target tolerance power, so that the power of the electrical signal received by the target circuit module 14 is less than or equal to the target tolerance power, and the target circuit module 14 can operate normally to avoid damage due to excessive power; if the power of the comparison voltage electrical signal is less than or equal to the power of the electrical signal transmitted by the power supply module 11, the comparator 121 can send a non-impedance adjustment signal to the switch unit 131 of the impedance adjustment module 13, and the non-impedance adjustment signal can be a low-level signal, then the switch unit 131 can It is connected to the second impedance adjustment branch 133 without an impedance element according to a low-level signal, and the input end of the switch unit 131 can also be connected to the power supply module 11 to receive an electrical signal. After the switch unit 131 is connected to the second impedance adjustment branch 133, the switch unit 131 can transmit the electrical signal to the second impedance adjustment branch 133, and the second impedance adjustment branch 133 directly transmits the electrical signal to the target circuit module 14, so that the power of the electrical signal received by the target circuit module 14 is less than or equal to the target tolerance power, and the target circuit module 14 can operate normally to avoid damage due to excessive power.

[0063] It is understandable that in other embodiments of the present application, the impedance adjustment signal may also be a low level signal, and the non-impedance adjustment signal may also be a high level, and the present application is not limited to this. In other embodiments of the present application, the impedance adjustment signal may also be other signals containing data, and the non-impedance adjustment signal may also be other signals containing data, and there may be a difference between the impedance adjustment signal and the non-impedance adjustment signal, but the present application does not specifically limit the types of the impedance adjustment signal and the non-impedance adjustment signal, that is, those skilled in the art may adjust their types according to actual conditions. As long as the impedance adjustment signal and / or the non-impedance adjustment signal can realize the control of the impedance adjustment module 13 to represent different impedances, it is acceptable.

[0064] like Figures 1 to 4 As shown, in an embodiment of the present application, the control module may include a resistor hybrid circuit 16, and the resistor hybrid circuit 16 may have a fourth end and a fifth end. The fourth end may be constructed as a control input end of the control module, and the fifth end of the resistor hybrid circuit 16 may be constructed as a control output end of the control module. The resistor hybrid circuit 16 may be used to output the control signal according to the electrical signal of the power supply end.

[0065] In this embodiment, the resistor hybrid circuit 16 can be a circuit formed by a plurality of resistors being hybridized, and has an impedance. The fourth end of the resistor hybrid circuit 16 can be a control input end, and can be used to receive an electrical signal sent by the power supply module 11. The resistor hybrid circuit 16 can adjust the impedance of the electrical signal after receiving the electrical signal sent by the power supply module 11 to obtain the electrical signal adjusted by the resistor hybrid circuit 16, and can transmit the electrical signal adjusted by the resistor hybrid circuit 16 to the control module as a control signal. If the power of the electrical signal sent by the power supply module 11 is greater than the target withstand power, the electrical signal adjusted by the resistor hybrid circuit 16 is greater than the preset electrical signal. After receiving the electrical signal greater than the preset electrical signal, the switch unit 131 will be connected to the first impedance adjustment branch 132 having an impedance element, so that the electrical signal of the power supply module 11 passes through the first impedance adjustment branch 132 having an impedance element in the impedance adjustment module 13. The regulating branch 132 performs impedance regulation on the electrical signal so that the power of the electrical signal output from the first impedance regulation branch 132 to the target circuit module 14 is less than or equal to the target tolerance power, so that the target circuit module 14 can operate normally; if the power of the electrical signal sent by the power supply module 11 is less than or equal to the target tolerance power, the electrical signal regulated by the resistor hybrid circuit 16 is less than or equal to the preset electrical signal, and after receiving the electrical signal less than or equal to the preset electrical signal, the switch unit 131 will be connected to the second impedance regulation branch 133 without impedance elements, so that the electrical signal of the power supply module 11 is transmitted through the second impedance regulation branch 133 without impedance elements in the impedance regulation module 13, so that the power of the electrical signal received by the target circuit module 14 is the same as the power of the electrical signal sent by the power supply module 11, so that the target circuit module 14 can operate normally.

[0066] In the embodiment of the present application, the resistor hybrid circuit 16 includes a plurality of resistors, and the plurality of resistors are connected in series and / or in parallel.

[0067] In this embodiment, the resistor hybrid circuit 16 is set according to the requirements, as long as the electrical signal output by the resistor hybrid circuit 16 can meet the application. Figure 2 and Figure 3 As shown, two different resistor hybrid circuits 16 are schematically shown.

[0068] In the embodiment of the present application, the target circuit module 14 includes at least one or more of a power amplifier, a filter, and a multiplexer.
