Class Information
Number: 326/49
Name: Electronic digital logic circuitry > Multifunctional or programmable (e.g., universal, etc.) > Field-effect transistor
Description: Subject matter wherein the logic 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).
