▸创新点3:仿真结果表明,18TSPC在能量-延迟空间中的效率是TGFF的两倍,显著提升了能效比(性能创新)。
▸创新点4:实验测量显示,在0.6V、25°C条件下,18TSPC相比TGFF整体动态功耗降低了68%,时钟动态功耗降低了73%,泄漏功耗减少了27%,进一步验证了其低功耗特性(性能创新)。
Abstract
Flip-flops (FFs) are essential building blocks of
sequential digital circuits but typically occupy a substantial
proportion of chip area and consume significant amounts of
power. This paper proposes 18-transistor single-phase clocked
(18TSPC), a new topology of fully static contention-free single-
phase clocked (SPC) FF with only 18 transistors, the lowest
number reported for this type. Implemented in 65-nm CMOS,
it achieves 20% cell area reduction compared to the conven-
tional transmission gate
