Abstract
A logic gate includes a plurality of pass gates forming a double rail pass gate XOR or reversing switch providing the same functionality as a conventional XOR gate. Consequently, the pass gate XOR can substitute for XOR gates in circuits such as a selector circuit and decision wait circuit, but with faster responses and fewer transistors than the conventional XOR gate. Each pass gate includes a P-type and an N-type transistor coupled in parallel. A control input and its complement are coupled to the gates of the transistors to selectively pass signals at the input of the pass gate to its output.
