ABSTRACT:
A compensating circuit (8) is used with a switched capacitor circuit (10) which includes a switched capacitor arrangement (12) and an op-amp (1) having a first input (14) coupled to a switched capacitor (11), a second input and an output (16). A sampling circuit (19,17,23) samples an error signal at the first input (14) of the op-amp (1) and an amplifier (15) coupled to receive the sampled error signal provides a compensation signal in dependence upon the sampled error signal. The compensation signal provides an offset signal for the second input of the op-amp (1), such that propagation of the error signal to the output (16) of the op-amp (1) is substantially reduced.
