ABSTRACT:
A high gain, field effect transistor differential amplifier including first and second cascade connected inverter stages and a feedback controlled source of current connected to each of the stages. High voltage gain is achieved by virtue of a positive feedback path connected between an output terminal of the differential amplifier and the source of current so that the current in each inverter stage is controlled.
