[0026] Currently, the design method of charge pumps mainly relies on manual design and experience accumulation. The traditional charge pump design process usually requires the designer to select a suitable charge pump structure according to the specific application requirements and perform detailed circuit design. This process not only takes a long time and is costly, but also requires a high level of professional experience for the designer.

[0027] Based on this, the embodiments of the present application provide a charge pump automatic generation method, device, storage medium and electronic equipment. Specifically, the charge pump automatic generation device can be integrated in an electronic equipment, which can be a server or a terminal and the like. The terminal can include a mobile phone, a wearable smart device, a tablet computer, a notebook computer, and a personal computer (PC) and the like. The server can be a single server or a server cluster composed of multiple servers, and can be a physical server or a virtual server.

[0028] For example, as shown in Figure 1 , the electronic equipment can obtain design parameters, including input voltage, target output voltage, target load capacitance and target load current; determine the target stage number of the charge pump to be generated according to the design parameters; call a single-stage pump template from a template library based on the target stage number, and parameterize the single-stage pump template according to the design parameters to generate a main circuit; select a peripheral circuit template matching the design parameters from the template library, and parameterize the peripheral circuit template according to the design parameters to generate a peripheral circuit; and merge the main circuit and the peripheral circuit according to the interface specification to generate the charge pump.

[0029] The technical solutions shown in the present application will be described in detail below through specific embodiments. It should be noted that the description order of the following embodiments is not limited as the priority order of the embodiments.

[0030] Please refer to Figure 2 , Figure 2 is a flowchart of the charge pump automatic generation method provided by the embodiments of the present application. The specific process of the charge pump automatic generation method can be as follows: 101. Obtain design parameters, including input voltage, target output voltage, target load capacitance, and target load current.

[0031] In this embodiment, the design parameters can be input according to the user's requirements, or automatically generated by the superior system or design tool. The design parameters include but are not limited to input voltage (V in ), target output voltage (V out ), target load capacitance (C load ), and target load current (I load ).

[0032] Among them, the input voltage refers to the voltage provided by the input end of the charge pump. Depending on the application, the value of the input voltage may vary. In memory applications, the input voltage is determined by the power supply voltage of the overall memory system, such as the commonly used 3.3V, 5V or other voltages.

[0033] Among them, the target output voltage is the voltage required to be provided by the output end of the charge pump. The target output voltage is usually determined according to the operating voltage of the used memory cell or load device. For example, a Flash memory cell usually requires 10V for erasing and writing, so the target output voltage can be 10V.

[0034] Among them, the target load capacitance refers to the load capacitance connected to the output end of the charge pump. The size of the target load capacitance usually depends on the characteristics of the load device, the working frequency and the dynamic response requirements of the circuit. By calculating the target load capacitance, the output stability of the charge pump can be optimized.

[0035] Among them, the target load current refers to the maximum current load that the output end of the charge pump can withstand. The target load current is crucial to the design of the charge pump and directly affects the current driving capability and efficiency of the charge pump. The designer can calculate the required switch device size and current transmission capability of the charge pump according to the target load current requirement.

[0036] 102. Determine the target number of stages of the charge pump to be generated according to the design parameters.

[0037] Among them, the target number of stages of the charge pump refers to the number of single-stage pumps that need to be connected in series in the charge pump in order to achieve the target output voltage. Each single-stage pump usually includes switch devices and capacitor units, which are used to complete charge transfer under the control of the clock signal. The output voltage of the single-stage pump is usually close to the input voltage, but will be affected by non-ideal factors such as switch device on-resistance and capacitor parasitic effects, resulting in actual voltage increase slightly lower than the theoretical value.

[0038] For example, in an ideal case, if the input voltage is 1.2V and the target output voltage is 3.6V, theoretically 3 single-stage pumps (each stage increases about 1.2V) are required, so the target number of stages Nstage =3. But in actual design, the target number of stages may need to be modified based on the theory to compensate for the loss and improve the output capability.

[0039] Specifically, the initial number of stages can be calculated according to the ratio of the target output voltage to the input voltage; the initial number of stages is corrected by using a transmission efficiency model or a lookup table correction result to obtain the target number of stages. When the transmission efficiency is low or the load is large, the number of stages can be automatically increased to ensure the output stability; when the input voltage is high or the load is light, the number of stages can be reduced accordingly to reduce power consumption and area overhead.

[0040] wherein the initial number of stages N init is calculated as follows: N init = Vin / Vout . Wherein V out is the target output voltage, V in is the input voltage, · represents the upward rounding operation.

[0041] wherein the transmission efficiency model is used to describe the energy transfer efficiency of the charge pump under different number of stages and different load conditions. The transmission efficiency model takes into account the on-resistance of the switching device, the capacitance charging and discharging loss, the parasitic capacitance influence and the clock frequency, etc. It can be established by circuit simulation or empirical formula.

[0042] For an ideal multi-stage charge pump, the relationship between the target output voltage and the input voltage can be expressed as: V out =N stage ×V in ×η(N stage , I load ). Wherein η(N stage , I load ) is the transmission efficiency function, reflecting the voltage loss ratio under different number of stages and load current conditions. When the actual output voltage calculated by the transmission efficiency model is lower than the target output voltage, the number of stages can be automatically increased; otherwise, the number of stages can be reduced to optimize the area and power consumption.

[0043] wherein the lookup table correction result refers to an empirical correction table established based on historical design data or simulation results in actual chip design or testing. When the input target output voltage, input voltage, target load current and other parameters are input, the recommended stage correction value can be quickly obtained by looking up the table.

[0044] For example, when the target output voltage is high (such as >5 V) or the load current is large, the lookup table result can indicate that the number of stages is increased by 1 to 2 stages; when the target output voltage is low or the load is light, the lookup table result can indicate that the number of stages is reduced by 1 to improve efficiency.

[0045] The table lookup correction can avoid complex real-time simulation calculation, and improve the speed and stability of the automatic generation process of the charge pump.

[0046] 103、Based on the target number of stages, a single-stage pump template is called from the template library, and the single-stage pump template is parameterized according to the design parameters to generate the main circuit.

[0047] Specifically, the number of single-stage pump templates to be called can be determined according to the target number of stages; then the corresponding single-stage pump templates are sequentially called from the template library according to the number; and finally, the single-stage pump templates are parameterized according to the design parameters to generate the main circuit.

[0048] In the embodiments of the present application, the template library contains a series of standardized single-stage pump templates and peripheral circuit templates. Each template defines a specific circuit structure, component configuration and parameter setting, which is called, customized and combined by the design system according to the requirements. The role of the template library is to accelerate the design process of the charge pump and ensure that the generated circuit meets the design specifications and performance requirements.

[0049] Each single-stage pump template defines a complete charge pump unit, including switching devices, energy storage capacitors, circuit connections and timing control, etc. The single-stage pump template is usually designed as a parameterizable structure, allowing the internal device parameters to be adjusted according to the design parameters.

[0050] The peripheral circuit template can include a selection bandgap reference module, a comparator module, a voltage divider module, a clock generation module, an output buffer module, and a load capacitor unit, etc. These peripheral modules are used to provide reference voltages, clock signals, load matching and other functions required by the charge pump. Each peripheral circuit template can also be parameterized according to the design parameters.

[0051] In some embodiments, the step of "parameterizing the single-stage pump template according to the design parameters to generate the main circuit" can specifically be adjusting the device parameters in each single-stage pump template according to the design parameters; establishing a cross-stage electrical connection relationship between the adjusted single-stage pump templates to generate the main circuit.

[0052] The adjustment of the device parameters can include adjustment of the switching device parameters, adjustment of the capacitor unit parameters, adjustment of the clock frequency parameters, and adjustment of the circuit layout, etc.

[0053] The adjustment of the switching device parameters can specifically be calculating and setting the size parameters of the switching devices in each single-stage pump template according to the target load current and the target output voltage.

[0054] In some embodiments, the size parameters of the switching devices can be calculated according to the following formula:

[0055] where W / L is the width-to-length ratio of the switching device, μ n is the electron mobility, V gs is the gate-source voltage; V th is the threshold voltage of the device.

[0056] In this embodiment, the size parameters of the switching device are dynamically adjusted according to the load current, output voltage, and material characteristics, which can ensure that it has sufficient driving capability and efficiency under specified operating conditions.

[0057] In some embodiments, adjusting the parameters of the capacitor unit can specifically be determining the number and capacity specifications of the capacitor units within each single-stage pump template based on the target load current and the target output voltage.

[0058] where the capacitor unit is mainly used for storing and transferring charges. Given the target load current, the total capacity of the capacitor unit needs to be sufficient to support the current demand of the load. Generally, the larger the capacity of the capacitor unit, the more charges it can store, thereby providing more stable current output.

[0059] According to the target load current and the target output voltage, the required total capacity of the capacitor unit can be calculated by the following formula:

[0060] where C total is the required total capacity of the capacitor unit, t charget is the time for the charge pump to charge (usually related to the operating frequency), I load is the target load current, V out is the target output voltage.

[0061] The capacity of each capacitor unit determines the amount of charge that a single capacitor can store. Specifically, the number of capacitor units can be determined according to the total capacity of the capacitor unit and the capacity of each capacitor unit.

[0062] For example, assuming the capacity of each capacitor unit is C unit , the number of required capacitor units can be calculated by the following formula:

[0063] where N capacitor is the number of required capacitor units.

[0064] In addition, in actual design, the size of the capacitor unit, the parasitic effect and the influence of the equivalent series resistance (ESR) of the capacitor unit on the charge transfer efficiency also need to be considered. Therefore, in addition to the capacity, the ESR of the capacitor unit also needs to be ensured to meet the requirements of the charge pump design to avoid excessive power consumption and unstable output when selecting the specification of the capacitor unit.

[0065] The clock frequency of the single-stage pump template has an important influence on the efficiency of charge transfer and the stability of output voltage. The clock frequency of the single-stage pump template can be adjusted according to the design parameters. The clock frequency directly affects the working efficiency and output waveform of the single-stage pump template. High-frequency clock can usually improve the efficiency of the single-stage pump template, but may increase the switching loss, so it is necessary to select a suitable clock frequency according to the target load current and target load voltage.

[0066] In some embodiments, the layout of the single-stage pump template can also be fine-tuned according to the design parameters, such as adjusting the position and connection method of the device, to reduce parasitic inductance and capacitance, optimize signal transmission path and reduce noise.

[0067] The purpose of establishing the cross-stage electrical connection relationship is to connect the output end of the previous single-stage pump template to the input end of the next single-stage pump template, forming a continuous chain of charge transfer. The output voltage of each single-stage pump template will be transferred to the input end of the next single-stage pump template through the cross-stage connection, until the output end of the last single-stage pump template produces the required target output voltage. In this process, the connection between the single-stage pump templates must meet the electrical specifications to ensure accurate signal transmission and avoid reverse current or signal loss.

[0068] 104. Selecting a peripheral circuit template matching the design parameters from the template library and parameterizing the peripheral circuit template according to the design parameters to generate a peripheral circuit.

[0069] As can be seen from the above embodiments, the peripheral circuit template can include a bandgap reference module, a comparator module, a voltage divider module, a clock generation module, an output buffer module and a load capacitor unit, etc.

[0070] Among them, the bandgap reference module is used to provide a stable reference voltage, which is usually used to provide a reference voltage for the operation of the charge pump; the comparator module is used to detect the relationship between the output voltage and the reference voltage, and to control the opening and closing of the charge pump; the voltage divider module is used to divide the input voltage by a predetermined ratio, which is used to adjust the voltage output; the clock generation module is used to generate a clock signal to drive the switching action of the charge pump; the output buffer module is used to match the target output voltage and the target load current, and to improve the driving capability of the circuit; the load capacitor unit is used to match the target load capacitance.

[0071] In some embodiments, parameterizing the peripheral circuit template according to the design parameters can include: The reference voltage output of the bandgap reference module, the threshold voltage of the comparator module, the voltage division ratio of the voltage divider module, and the working frequency of the clock generation module are configured according to the design parameters. The required number of load capacitance units is calculated and instantiated based on the target load capacitance to be combined to form the target load capacitance.

[0072] It should be noted that during the construction of the peripheral circuit, it is necessary to ensure that the electrical interfaces between the modules are correctly connected and that they can work cooperatively. The specific connection mode between the modules can be referred to the prior art, which will not be described one by one here.

[0073] 105、According to the interface specification, the main circuit and the peripheral circuit are merged to generate a charge pump.

[0074] In some embodiments, the merging process can include interface matching, electrical connection, and verification steps.

[0075] Specifically, before merging the main circuit and the peripheral circuit, it is necessary to first check the interface parameters between the main circuit and the peripheral circuit to ensure that the electrical connection is correct and there is no conflict. After confirming that the interface parameters match, the main circuit and the peripheral circuit can be electrically connected according to the interface specification to form a complete charge pump circuit. After completing the electrical connection, the circuit can also be verified (such as circuit function verification, timing and signal integrity check, power and heat analysis, etc.) to ensure that the circuit functions normally and works stably.

[0076] After verification, a complete charge pump circuit netlist and layout file can be generated. These files include the connection relationship between the modules of the charge pump, component size, layout information, etc., for subsequent layout design, simulation verification, and chip implementation.

[0077] In summary, the charge pump automatic generation method provided by the embodiments of the present application includes obtaining design parameters, the design parameters including input voltage, target output voltage, target load capacitance, and target load current; determining the target stage number of the charge pump to be generated according to the design parameters; calling a single-stage pump template from a template library based on the target stage number, and parameterizing the single-stage pump template according to the design parameters to generate a main circuit; selecting a peripheral circuit template that matches the design parameters from the template library, and parameterizing the peripheral circuit template according to the design parameters to generate a peripheral circuit; and merging the main circuit and the peripheral circuit according to the interface specification to generate a charge pump. The embodiments of the present application can automatically generate a main circuit and a peripheral circuit according to design parameters, and merge the main circuit and the peripheral circuit into a charge pump without the need for human intervention, thereby improving the generation efficiency of the charge pump.
