A differential circuit stage that produces a difference signal from two input signals, and a gain stage which applies a gain to the difference signal, the gain stage having a pair of transistors connected to balance gate-leakage current in the differential stage. A first transistor is connected to the differential stage and the first transistor is sized to provide current to balance the differential stage. A second transistor is connected to the first transistor and the second transistor is sized to eliminate leakage current in the first transistor.
