Abstract :
In this paper, we propose a 3-input XOR/XNOR circuit for low-voltage, low-power applications. Several existing 3-input XOR/XNOR circuits and this proposed circuit have been fully simulated using HSPICE with a 0.35 μm CMOS technology from 3.3 V down to 2 V supply voltage. The simulation results show that the proposed circuit has the benefits of better driving capability and lower power consumption as well as the least power-delay product than those of the existing circuits. Additionally, this circuit has a full voltage-swing in all internal nodes under 2 V supply voltage or less. Thus, the proposed circuit is suitable for low-voltage, low-power applications
