ABSTRACT:
An operational amplifier is provided having two input legs and a reference leg. In order to eliminate any input offset voltage between the two input legs, the reference leg is balanced against the first input leg and then against the second input leg so that the first input leg is thereby balanced against the second input leg and any offset voltage is significantly reduced or eliminated.
