Abstract
Abstract
Optimizing the power consumption of flip-flops (FFs), as essential components of sequential digital circuits, can significantly reduce the overall energy usage of digital systems. This paper introduces an ultra-low-power true single-phase clocked (TSPC) flip-flop with a 25-transistor design (29 transistors with a reset function). By eliminating redundant charging and discharging and addressing floating nodes through transistor-level optimization, the design achieves a fully static, contention-free operation. Implemented in CMOS technology, demonstrate that the proposed circuit offers exceptionally low energy consumption, making it ideal for energy-efficient applications.
Keywords: low power, flip-flop.
