| 摘要 |
A digital circuit configured to receive three or more input signals and produce an output signal corresponding to either an XOR or XNOR of the input signals. In one embodiment of the invention, the circuit includes a first section connected in series with a second section to form a three-input XOR or XNOR gate. The first section is a two-input XOR or XNOR circuit having no more than eight transistors, including two transmission gate pairs. The second section is a two-input XOR or XNOR circuit having no more than six transistors, including one transmission gate pair.
