Class Information
Number: 326/83
Name: Electronic digital logic circuitry > Interface (e.g., current drive, level shift, etc.) > Current driving (e.g., fan in/out, off chip driving, etc.) > Field-effect transistor
Description: Subject matter wherein the current driving circuit includes 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).
