Class Information
Number: 326/109
Name: Electronic digital logic circuitry > Function of and, or, nand, nor, or not > Bipolar and fet
Description: Subject matter wherein the logic circuit includes two types of transistors: (a) a bipolar transistor having at least three electrodes (emitter, base, and collector), two potential barriers, and wherein a controlled current flow comprises both majority and minority carriers (i.e., holes and electrons) and (b) 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 electrical field applied to the semiconductor from a control electrode (gate).
