A 2.4 GHz ISM-band Highly Digitized Receiver based on a Variable Gain LNA and a Subsampled ADC

Abstract : In this paper, we present a complete multi-standard receiver based on a variable-gain LNA and an RF subsampled Sigma-Delta ADC. The receiver includes an RF digital down-conversion mixer and a polyphase multistage multi-rate decimation filter. The receiver is measured for 3 different standards in the 2.4 GHz ISM-band. Measurement results show that the receiver achieves 79, 73 and 63 dB of dynamic range for the Bluetooth, ZigBee and WiFi standards respectively. The complete receiver, implemented in 130 nm CMOS process, has a 300 MHz tunable central frequency and consumes 63 mW under 1.2 V supply.
