Class Information
Number: 327/543
Name: Miscellaneous active electrical nonlinear devices, circuits, and systems > Specific identifiable device, circuit, or system > With specific source of supply or bias voltage > Stabilized (e.g., compensated, regulated, maintained, etc.) > Using field-effect transistor
Description: Subject matter wherein the circuit includes only one type of transistor which is a unipolar transistor in which current carriers are injected at a source terminal and pass to a drain terminal through a channel of semiconductor material whose conductivity depends largely on an electric field applied to the semiconductor from a control terminal (gate).
