A 1.9GHz Single-Chip CMOS PHS Cellphone

Abstract

A single-chip CMOS PHS cellphone, fabricated in a 0.18mum CMOS process, implements all handset functions including radio, voice, audio, CPU, and digital interfaces. The IC has +4dBm EVM-compliant transmit power, -106dBm receiver sensitivity, and 15mus synthesizer settling time. It draws 81 mA from a 1.8V supply while occupying 35mm² of chip area
