ABSTRACT:
An operational amplifier circuit for use in high density L.S.I. chips incorporates four solid state silicon devices in a flip-flop-like configuration including a source follower function on the input side of the circuit while a depletion transistor provides for positive feedback and prohibits the circuit from latching thereby the circuit is locked to operate in a transition zone between switching states, providing a linear high gain function which can be operated as an amplifier.
