(under subclass 252) Subject matter wherein a field effect transistor (FET) is utilized in the circuit with the differential amplifier.
(1) Note. A field effect transistor (FET) is a semiconductor device in which the resistance between two terminals, the source and drain, depends on a field produced by a voltage applied to the third terminal, the gate.
(2) Note. The field may modulate a depletion region, as in a junction FET, or it may cause a conductivity change in a channel, as in a MOS-FET.
