49 mW 5 Gbit/s CMOS receiver for 60 GHz impulse radio

A 5 Gbit/s CMOS receiver for 60 GHz impulse radio is realised. It contains a fully differential envelope detector for differential inputs, a current mode offset canceller for robustness against PVT variations, and a high-speed comparator with hysteresis for noise immunity. The receiver is fabricated using a 90 nm CMOS process with a size of 950 750 m. The total power consumption of the receiver is 49 mW at 5 Gbit/s.
