Cmos xor gate by circuit diagram. For example here is the schematic diagram for a cmos nand gate. The output of a xor gate is equal to 1 if the two inputs are both different and is 0 if they both have the same logic value.
The principle of operation of the circuit is exact dual of the cmos two input nor operation.
The circuit diagram of the two input cmos nand gate is given in the figure below. Both are controlled by the same input signal input a the upper transistor turning off and the lower transistor turning on when the input is high 1 and vice versa. Cmos xor gate by circuit diagram. For example here is the schematic diagram for a cmos nand gate.
