摘要

This article presents a 2.4-/5.7-GHz dual-band low-power direct-conversion CMOS RF receiver for the 802.11a/b/g WLAN applications. The RF receiver includes a low noise amplifier (LNA) with dual input stages and dual switches for each of 2.4/5.7-GHz applications. This design can substitute the use of two LNAs in conventional structure and eliminate the use of the costly external band-select switches. It also alleviates the difficulty of single matching for multiple frequency bands. The RF receiver also includes a Gilbert-cell-based broadband mixer which is designed to be both low power consumption and relatively high conversion gain. Fabricated in 0.18-μm CMOS technology, the RF receiver exhibits a conversion gain of 25.8/20.6 dB, DSB noise figure of 4.4/5.6 dB, and input IP3 of -18/-12.5 dBm at 2.4/5.7 GHz frequency band, respectively. The measured EVM for IEEE 802.11a/b/g is 1.2/1.6/1.1% at data rate of 11/54/54 Mbps. The power consumption under 1.8 V supply is 10.6 mW for the 2.4 GHz mode, and 17.2 mW for the 5.7 mode.
