DEFINITION

Classification: 326/89

Bipolar transistor:

(under subclass 82) Subject matter wherein the current driving circuit includes a semiconductor device having at least three electrodes (emitter, base, and collector), two potential barriers (npn or pnp), and having a controlled current flow of both majority and minority carriers (i.e., holes and electrons).
