Abstract
Circuits are illustrated using CMOS design techniques for incorporating N and P channel transistors into a circuit to obtain the functions of exclusive OR and exclusive NOR signal generation. This is accomplished by utilizing a given logic value signal as a control signal to pass the other input signal for three of the four possible logic value conditions. The fourth condition must generate the output signal from a selected one of the input signals, through the use of an inverter.
