Abstract :
This paper presents a new design of a clock gater standard cell. The circuits are designed and laid out according to the TSMC 250-nm, 2.5 V process. By using a differential latch rather than a transmission gate latch in the circuit, the layout area can be reduced by 20%. Computer simulation including parasitics shows that there is also a reduction in power consumption, the percentage decrease depends on the enable signal activity factor.
