Area-Efficient Gray Code Counter Design Using Hybrid Flip-Flop

Chip area plays an important part in the advancement of semiconductor technology, enabling integrated circuits to get smaller and smaller over time. Numerous advantages result from this reduction, including higher production yield, better energy efficiency, better system performance, and lower component density in packaging. We are Utilizing [2] 18-transistors hybrid flip-flop structure to design a Gray code counter (GCC) [2] with asynchronous clock input, the design is useful for high-performance implementations, Gray code is a unit-distance coding technique that significantly decreases error propagation in communication networks by altering only one bit every transition. The suggested design outperforms traditional Gray code counters by reducing the area by about 30.49%. The implementation operates in the voltage range of 0.7-1.2V and has a transient response time of 300ns. Cadence Virtuoso in 45nm is used to accomplish it.
