Abstract
A CMOS transmission gate circuit having a pass transistor and a feedback transistor is coupled across a logic gate. The pass transistor is responsive to a control signal for passing a logic signal. The feedback transistor aids the pass transistor in passing a first logic voltage level when the output signal of the logic gate is a second logic voltage level. Further, the speed performance of the CMOS transmission gate circuit is not degraded if the feedback transistor fails.
