A low-power multi-band CMOS RF receiver front-end for ubiquitous sensor network applications

This paper presents the design and experimental results of a low-power multi-band RF receiver including a multi-band low-noise amplifier (LNA) and a down-conversion mixer based on the IEEE 802.15.4 standard for sensor node applications. A multi-band LNA with two inputs is tuned to two resonant frequ...

Description
Summary:This paper presents the design and experimental results of a low-power multi-band RF receiver including a multi-band low-noise amplifier (LNA) and a down-conversion mixer based on the IEEE 802.15.4 standard for sensor node applications. A multi-band LNA with two inputs is tuned to two resonant frequencies by controlling the voltage on a switched MOS. The implemented RF receiver front-end achieves a maximum voltage conversion gain of 38 and 30 dB, NF of 6.2 and 9.2 dB at the 868/915 MHz and the 2.45 GHz bands, respectively. The RF receiver front-end dissipates total 3.0 mA (including I/Q mixers) under supply voltage of 1.8 V at both operation bands.
