A 2.4GHz ISM-Band Digital CMOS Wireless Transceiver
with an Intra-Symbol Adaptively Intermittent Rx

 

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: 4.5mW, BER: 4.1x10-5, received signal intensity: -73dBm, 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 -40.6dBc) and a digitally controlled direct RF carrier phase modulator (ACPR<-40dBc).
