ABSTRACT:
A voltage regulator providing smooth variation of an absorbed current having a first capacitor parallel-connected to a load, which is in turn connected to a supply voltage; a transconductor coupled between the supply voltage and the load and whose output voltage supplies the load; a differential amplifier coupled between the output of the transconductor and the supply voltage, and further coupled to the input of the transconductor, a second capacitor coupled between the supply voltage and the input of the transconductor; and a pair of diodes coupled between the output of the transconductor and the first capacitor and configured to introduce a zero in the transfer function of the voltage regulator that is suitable to compensate for a pole generated by the first capacitor.
