Abstract :
The first achievement of intra-symbol adaptively intermittent receiver has been developed with an inductor-less LNA by 90-nm digital CMOS, and Rx characteristics have been measured (Rx power: 4.5 mW, BER: 4.1times10-5, received signal intensity: -73 dBm, when Rx is enabled within only 8.2% of a single symbol period) with an on-chip stair-like shaping PA (3rd order harmonics of -40.6 dBc) and a digitally controlled direct RF carrier phase modulator (ACPR<-40 dBc).
