WebThe paper demonstrates the circuit of a low power D flip-flop serial in/parallel out (DFF SIPO) based shift register design. The flip-flops (FF's) consumption of casual logic power in a SoC chip (system on chip) commonly overpasses 50% as long the input and the output are in the same state thanks to the redundancy transition of interior loops. Conventional … WebMar 8, 2024 · The DFF is constructed using two latches , as shown in Figure 2b. The internal signals q1, q2, q3 and q4 with a duty cycle of 50% are the divide-by-eight clocks of CK master such that a clock pulse signal CK div8 with a duty cycle of 12.5% is obtained through AND logic operation.
