Abstract— Digitally controlled delay line is a digital circuit used to provide the desired delays for a circuit whose delay is controlled by a digital controlled word.. Glitches are the most considerable factor that limits the use of DCDL in many applications such as DLL and clock generators. The NOR-Based circuit eliminates the glitches. This circuit uses control bits which can be generated by using dual triggered flip-flop. This flip-flop consumes more power. In the proposed method, power consumption is reduced by using dual edge triggered sense amplifier flip-flop has been reduced using clock-gated sense-amplifier flip-flop. The simulations are done using Microwind analysis software tools. Our proposed system simulations are done under CMOS 0.12m technology and the results are compared with other conventional flip-flops. Hence, our proposed system is showing better output than the other flip-flops.
