Abstract
A four transistor XOR or XNOR gate includes an inverting stage and a non-inverting stage. The transistors in each stage are coupled so as to enable changing inputs and existing inputs to drive the output in the same direction. The XOR gate and XNOR gate take advantage of a known order or inputs to reduce the delay of the gate.
