ABSTRACT:
An amplifier having differential inputs and outputs that includes: an input differential pair; a first and a second single ended output differential amplifier that each receive the outputs of the differential pair; a buffer stage connected to each single ended output differential amplifier whose output constitutes an output of the amplifier; a unique means for adjusting the quiescent current supplied by the single ended differential amplifiers to the buffer stages that results in the adjustment of the common mode voltage to a required value.
