Abstract :
A fully integrated receiver in a 0.13 mum CMOS technology including on-chip power amplifier (PA) for digital cordless telephone standards is presented. The implemented frequency synthesizer shows robustness against PA coupling, excellent phase noise performance and fast settling time. The frequency tuned LNA and IF-filter is designed to cover the frequency bands from 1.8 GHz to 2.5 GHz. The fully integrated receiver deploys a low Intermediate Frequency (IF) architecture with a very low noise, low current consumption front-end and a complex band pass filter for channel selection. The measured receiver sensitivity level is P0.1% = -96 dBm. The transceiver uses ITX = 35 mA in transmit mode and IRX = 25 mA in receive mode from a regulated VTRX = 1.5V supply. The transceiver is developed as a part of a complete System-on-Chip (SoC) cordless phone.
