Review of innovations in low-power flip-flops based on the development of innovative logic gates

Abstract

Integrated circuits have advanced quickly alongside the semiconductor industry's tremendous growth. The primary design considerations for each circuit in a VLSI data path are minimization of area and power consumption. As a very important logic unit in the integrated circuit, reducing the flip-flop's power consumption is of great significance for improving the performance of the whole circuit. There are many ways to reduce the power consumption of the flip-flop. This paper reviews several new low-power flip-flop designs using methods to improve the logic structure of flip-flops and their logic gates, including a reversible flip-flop design with reversible gates, a flip-flop design with memristors, and a sense amplifier-based flip-flop. The analysis shows that all three options for improving the logic gate can reduce the power consumption of the flip-flops and also have a positive effect on reducing the size of the device.
