Abstract
An integrator circuit utilizing an operational amplifier (19) and switched capacitor elements (11, 13 and 16) in place of resistors in such a manner as to provide compensation for voltage offsets present in the operational amplifier resulting in an output voltage (V.sub.OUT) free from the effects of voltage offsets inherent in operational amplifiers.
