ABSTRACT:
Imbalances in the potential appearing across the drain electrodes of source coupled FET transistors arranged in a differential amplifier configuration tends to produce input offset voltages. Where the drain electrodes of the transistors are coupled to a current mirror load for converting balanced signals to a single ended output which in turn is applied to a common source amplifier, the input offset may be nulled by differentially adjusting the drain current of the common source amplifier against the source current of the differential stage.
