A differential amplifier suited for use in operational amplifiers employing both FET's and junction transistors has a superior gain-bandwidth product for given input offset specification. Source-coupled FET's accept input signals at their gate electrodes. Each FET is included in a composite transistor device together with a direct coupled, inverting, current amplifier having an input terminal to which the drain electrode of the FET is coupled and having an output terminal coupled to the source electrode of the FET.
