So, the analysis is done by optimizing the delay, which results in fast processing and low average energy consumed. In this paper, 1-bit hybrid full adder is designed using Complementary Metal Oxide Semiconductor (CMOS), transmission gate and pass transistor logic. The circuit is implemented on Cadence Virtuoso 6.1 tool in 180-nm technology with 1.8V supply voltage. The delay (14.32ps) is found to be very small with significant reduction in the Power-Delay-Product(0.904fJ). The number of transistors is reduced; resulting in area optimization. The proposed 1-bit hybrid full adder design is found to be very fast as compared to the previous existing full adder circuits.
