Data Distinguisher Module Implementation using CMOS Techniques

Comparator plays a vital role in many IC applications, Microprocessors, computer systems etc. Hence it is desirable to design a comparator block with low power consumption and high speed performance.In this paper a novel architecture of 32-bit comparator using Complementary metal-oxide semiconductor logic is proposed and computed its delay and power metrics. Further it is compared with the full adder based 32-bit comparator. From the analysis we derive the comparison between proposed and the conventional comparator. The complete designing of architectures and their result analysis was done in cadence virtuoso tool at 180 nm technology. Simulation results show that there is reduce in power consumption of 90% when compared to the conventional full adder based comparator.
