Class Information
Number: 341/136
Name: Coded data generation or conversion > Analog to or from digital conversion > With particular solid state devices (e.g., gunn effect device, josephson device, drift transistor, using solid state active devices as impedances) with other at longer intervals) > Field effect transistor
Description: Subject matter using a semiconductor device in which the resistance between two terminals, the source and the drain, is switched by a voltage applied to the third terminal, the gate, and the said resistance is determined by device geometry.
