Abstract :
A 1.2 GHz dual-modulus prescaler IC fabricated with 0.8 μm CMOS technology is presented in this paper. The dual-modulus prescaler includes a synchronous counter (divide-by-4/5) and an asynchronous counter (divide-by-32). A new dynamic D-flip-flop (DFF) is developed for the high-speed synchronous counter. The maximum operating frequency of 1.22 GHz with power consumption of 25.5 mW has been measured at 5 V supply voltage
