US Patent 11755798 Logic circuits with reduced transistor counts
A logic circuit including first and second inverters, first and second NAND circuits, a transmission gate, and a transmission-gate-substitute (TGS) circuit, and wherein: for each of the first and second NAND circuits, a first input is configured to receive corresponding first and second data signals, and a second input is configured to receive an enable signal; the first inverter is configured to receive an output of the first NAND circuit; the transmission gate and the TGS circuit are arranged as a combination circuit which is configured to receive an output of the second NAND circuit as a data input, and outputs of the first inverter and the second NAND circuit as control inputs; the second inverter is configured to receive an output of the combination circuit; and an output of the second inverter represents one of an enable XOR (EXOR) function or an enable XNR (EXNR) function.
