Class Information
Number: 326/115
Name: Electronic digital logic circuitry > Function of and, or, nand, nor, or not > Field-effect transistor (e.g., jfet, etc.) > Source-coupled logic (e.g., current mode logic (cml), differential current switch logic (dcsl), etc.)
Description: Subject matter wherein the logic function unit includes an arrangement in which the source channel of plural input transistors are connected to the source and the gate of a referenced transistor, and are commonly grounded (biased) through a current source for performing a nonsaturated, differential logic operation.
