Abstract
An improved high gain, field effect transistor differential amplifier including first and second cascade connected inverter stages, a feedback controlled source of current connected to each of the stages, including a source of controlled positive feedback for increasing the voltage gain. A positive feedback path is connected between an output terminal of the differential amplifier and the source of current so that the current in each inverter stage is more precisely controlled.
