Abstract

A dual-mode, triband RF front-end receiver for GSM-900, DCS-1800 and IEEE 802.11b/g is introduced. With advanced architecture selection and frequency plan, only a single VCO and frequency synthesizer are required for both GSM/GPRS cellular and IEEE 802.11b/g WLAN. The receiver front-end has been realized in a 0.25 μm CMOS process. It dissipates about 30 mA from a 2.7 V supply for all modes and exhibits noise figures of 3 dB for the GSM-900 band, 5.9 dB for the DCS-1800 band, and 5.7 dB for 2.4 GHz WLAN.
