Low-Power and Area-Efficient Shift Register
Using Pulsed Latches
Abstract—This paper proposes a low-power and area-efficient shift register using
pulsed latches. The area and power consumption are reduced by replacing flip-
flops with pulsed latches. This method solves the timing problem between pulsed
latches through the use of multiple non-overlap delayed pulsed clock signals
instead of the conventional single pulsed clock signal. The shift register uses a
small number of the pulsed clock signals by grouping the latches to several sub
shifter registers and using additional temporary storage latches. A 256-bit shift
register using pulsed latches was fabricated using a 0.18 CMOS process with . The
core area is . The power consumption is 1.2 mW at a 100 MHz clock frequency.
The proposed shift register saves 37% area and 44% power compared to the
conventional shift register with flip-flops.
