A Comparative Performance Analysis of Various CMOS Design Techniques for XOR and XNOR Circuits

XOR and XNOR gates play an important role in digital systems. XOR & XNOR logic gates are basic building blocks of many arithmetic circuits. The XOR and XNOR circuit is implemented in pass transistor logic, static CMOS logic, transmission gate logic. The design of the XOR & XNOR circuits based on TSMC 32nm process models at the supply voltage 0.9V is simulated using HSPICE. Due to low power consumption and high speed these design circuits are suitable for arithmetic operations and VLSI applications. Hence comparison of delay & power is obtained in this paper for various design techniques of logic gates.
