DEFINITION

Classification: 326/75

Bipolar transistor:

(under subclass 63) Subject matter wherein the interfacing circuit includes a semiconductor device having at least three electrodes (emitter, base, and collector), two potential barriers, and a controlled current flow of both majority and minority carriers (i.e., holes and electrons).
