An ultralow-power-consumption, high-speed, GaAs 256/258 dual-modulus prescaler IC

A GaAs divide-by-256/258 dual-modulus static prescaler is described. The pr escaler has a pulse-swallow counter-type architecture and quasi-differentia l switch hip-hops as its basic circuit architecture. For the input buffer c ircuit, a circuit called a source-coupled push-pull circuit has been develo ped that can generate high-frequency complementary signals from a single-ph ase signal at a low supply voltage. This IC operates at up to 14.5 GHz with a power consumption of 22 mW, The power consumption is less than 1/50 of t he previously reported prescalers that can operate above 10 GHz.
