Abstract :
This paper describes a GaAs divide-by-256/258 dual-modulus static prescaler IC. The prescaler has a pulse swallow counter-type architecture and quasi-differential switch flip-flop (QD-FF) as its basic circuit architecture. For the input buffer circuit, we have developed a circuit that we call a Source coupled push-pull circuit (SCC), which can generate high-frequency complementary signals from a single phase signal at a low supply voltage. The IC operates at up to 14.5 GHz with a power consumption of 22 mW. The power consumption is 1/100 that of a previously reported prescaler.
