Abstract
A circuit and a method for power conversion and for generating an output voltage in accordance with a reference voltage are presented. The power converter has a circuit for filtering the output voltage, an error amplifier circuit that compares the reference voltage and the filtered output voltage for generating an error voltage as a result of the comparison. There is a circuit for driving one or more switching devices in dependence on the error voltage. The error amplifier circuit has a first differential circuit and a first bias current generation circuit for generating a first bias current for the first differential circuit, a second differential circuit and a second bias current generation circuit for generating a second bias current for the second differential circuit, and a circuit for redistributing the first bias current to the second differential circuit or redistributing the second bias current to the first differential circuit.
