Abstract
An integrated amplifier that can be use as a standard cell which includes a differential input stage and an output stage to provide an increased input common mode range. The differential input stage includes a pair of differentially configured PMOS transistors coupled to a differential-to-single ended converter comprised of a pair of NMOS transistor. A PNP transistor is formed in the integrated circuit having its base-emitter junction coupled between the drain and gate of one of the NMOS transistors to thereby establish therewith a voltage at the drain of the PMOS device coupled to the inverting input of the amplifier sufficient to maintain the latter in its linear operating range as the input thereto is common moded to ground.
