Abstract :
A new reduced clock-swing flip-flop, named NAND-type Keeper Flip-Flop (NDKFF) is proposed. Compared with other conventional reduced clock-swing flip-flops such as HSFF and RCSFF, NDKFF features a simple configuration, which does not have additional clock drivers or does not have additional nand/or p-wells. Compared with the hybrid-latch flip-flop, 52% of the flip-flop power and 64% of the clocking power are saved in the case of 0.25 μm CMOS technology. Moreover CLK-to-Q delay is comparable to that of conventional C2MOS-type master-slave flip-flop.
