Abstract

A fully-integrated direct-sequence spread-spectrum (DSSS) CMOS transceiver for 2.4-GHz ISM band is presented. It integrates a RF transceiver, a frequency synthesizer, baseband filters, digital signal processing, an adaptive differential pulse-code modulation (ADPCM) codec, and a programmable PA pre-driver. The transceiver chip achieves a measured sensitivity of -103 dBm and an output power of 3 dBm. The total chip area is 3.4 times 3.3 mm² in a standard RF 0.18-mum CMOS technology
