Abstract: High-level integration of the Bluetooth and 802.11b WLAN radio systems in the 2.4-GHz ISM band is demonstrated in scaled CMOS. A dual-mode RF transceiver IC implements all transmit and receive functions including the low-noise amplifier (LNA), 0-dBm power amplifier, up/down mixers, synthesizers, channel filtering, and limiting/automatic gain control for both standards in a single chip without doubling the required silicon area to reduce the combined system cost. This is achieved by sharing the frequency up/down conversion circuits in the RF section and performing the required baseband channel filtering and gain functions with just one set of reconfigurable channel filter and amplifier for both modes. A chip implemented in 0.18-μm CMOS occupies 4 × 4 mm 2 including pad and consumes 60 and 40 mA for RX and TX modes, respectively. The dual-mode receiver exhibits -80-dBm sensitivity at 0.1% BER in Bluetooth mode and at 12-dB SNR in WLAN mode.
