摘要:
A charge pump driver circuit comprises an output stage and a current generator component. The output stage is arranged to receive at an input node thereof a control current signal and comprises a resistance network coupled between the input node thereof and a reference voltage node and arranged to provide a resistive path through which the control current signal flows. The output stage is arranged to generate at an output node thereof a charge pump control voltage signal based on the voltage level at the input node thereof. The current generator component is arranged to receive an indication of a voltage level of a charge pump output signal, and to generate a feedback current dependent on the voltage level of the output signal, wherein the feedback current is injected into the resistive path of the resistance network through which the control current signal flows.
