Abstract :
Exclusive-OR and exclusive-NOR gates are important in digital circuits. This paper proposes a new set of low power 4-transistor XOR/XNOR gates. Simulations have been performed on the circuits along with 10 other XOR gates. The results show that the new XOR/XNOR gates consistently consume less power than any other XOR/XNOR gate known at the time of publication. In fact, it consumes up to more than 3 times less power than the complementary CMOS implementation and can have 34% better propagation delay. The static energy-recovery XOR gate, which is the second least power-consuming, dissipates 10% more power than the new gates
