ABSTRACT:
An operational amplifier has one noninverting input lead (116), and two inverting input leads (117a, 117b). One of these inverting input leads (117a) is utilized to compensate for the effects of the inherent offset voltage (V.sub.off) of the operational amplifier, and the second inverting input lead (117b) receives an input signal to be amplified or compared.
