.~.~ Pass transistor logic or transmission gate logic
DEFINITION
Classification: 326/113
Pass transistor logic or transmission gate logic:
(under subclass 112) Subject matter wherein a field-effect transistor performs a logic function using power from two signal inputs which feed through a gate and a source (or drain) terminals with an output taken at the drain (or source) terminal which is an AND function of the two signal inputs.
(1) Note. The use of pass transistor logic saves power and reduces transistor numbers, but lowers the operational speed.
(2) Note. Transmission gate logic includes at least two field-effect transistor elements used as pass transistors, each having a channel of conductivity type opposite that of the other (i.e., complementary FET's).
