ABSTRACT:
An integrator with a sampling stage at the input side has a first capacitor with associated electronic switches and has one or more amplifier stages each having a feedback path containing a second capacitor which is connected to the output of the sampling stage. The integrator has a first polarity commutator interconnected between the output of the sampling stage and the input of the first amplifier stage and a second polarity commutator at the output of one of the amplifier stages, the second polarity commutator being operated synchronously with the first polarity commutator. By periodic actuation of the polarity commutators, the low frequency noise voltage components, having amplitudes which vary minimally within a polarity reversal period, cancel when the integration results of successive periods of opposite polarity are added and are thus substantially eliminated.
