Design of low delay low power hybrid logic based flip-flop using FinFET

The need for a low-power and high-speed technology for computation of digital signals is rising due to the fast growth of technological innovations. Flip-flops serve as fundamental elements in signal processing technologies. Hybrid logic has great potential for constructing flip-flop circuits because of its minimal transistor count as well as low-power properties.The present investigation presents a design for a tiny and low-power hybrid flip-flop that operates fully statically. The design has been developed by utilizing different circuitry-reduction techniques. It incorporates a hybrid logic approach combining pass transistor logic to decrease circuit complexity. The ongoing work utilizes a hybrid logic with low delay and low power to generate flip-flops. The proposed flip-flop design significantly decreases latency compared to the existing master-slave flip-flops. This flip-flop remains immune to clock overloading, resulting in reduced power consumption. Reducing the quantity of PFET (P-channel Field Effect Transistor) transistors enhances the circuit's delay, area, and power consumption. Implementing these circuit optimization techniques yields several benefits, such as reduced CLOCK-to-OUT and DIN-to-OUT node delays, decreased average power consumption, lower leakage power, and a transistor count of only 18. The results were achieved using Cadence Virtuoso at 18nm finFET technology, with varied process corners, supply voltages ranging from 0.7V to 1V, and temperatures ranging from -50°C to 75°C. This study also presents a Monte Carlo simulation of power consumption, leakage, and delay for the suggested flip-flop. According to the simulations, the recommended flip-flop exhibits exceptional stability. The recommended flip-flop has lower power usage by at least 17.95% compared to standard architectures due to the lower number of PFET transistors.
