Pass Transistor Circuit. This article presents efficient pass transistor based implementations of important digital functionality. The term pass transistor logic refers to a different form of mosfet circuitry that doesn t generate logic high and logic low voltages in the way that typical cmos circuitry does.
The operating conditions for the transistor are set up in the normal way. As the name implies ptl uses transistors as switches that pass or block a signal. In complementary cmos logic primary inputs are allowed to drive only gate terminals.

R2 and r3 are used to set up the bias point for the base of the transistor. The operating conditions for the transistor are set up in the normal way. Transistors are used as switches to pass logic levels between nodes of a circuit instead of as switches connected directly to supply voltages. In complementary cmos logic primary inputs are allowed to drive only gate terminals.
