Abstract
A switched-capacitor amplifier comprises a comparator, sample and amplification capacitors and a controller to control charge and discharge current sources in dependence on an output signal of the comparator. A closed loop control circuit is configured to determine the delay of the comparator and control an offset of the comparator in response to the determined delay.
