ABSTRACT:
An apparatus is provided. The apparatus comprises an error amplifier that amplifies the difference between a reference voltage and a feedback voltage, a first variable impedance circuit coupled to the error amplifier that receives a control voltage from the error amplifier, a charge pump coupled to the variable impedance that receives an input voltage from the variable impedance, and a Miller compensator coupled to the charge pump and to the first variable impedance circuit. The Miller compensator receives the output voltage and output current from the charge pump. It also outputs the feedback voltage, adjusts the control voltage, and has a zero-pole that is proportional to a power of the output current of the charge pump.
