Class Information
Number: 326/55
Name: Electronic digital logic circuitry > Exclusive function (e.g., exclusive or, etc.) > With field-effect transistor
Description: Subject matter including 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).
