Abstract :
This paper presents a low-power transceiver with a reconfigurable sliding-IF (intermediate frequency) architecture targeted for wireless body area networks hubs covering 400 MHz and 2.4 GHz bands. By using this architecture, a 1608-1988 MHz PLL synthesizer with only 21% tuning range can fully cover all the available bands around 400 MHz and 2.4 GHz as defined by IEEE 802.15.6 NB (narrow band) and ZigBee. The dual-band transceiver has been designed in 0.18 μm CMOS process. The design consists of a receiver with a wideband front-end and a reconfigurable amplifier-mixer, a transmitter with a reconfigurable two stage full quadrature mixer, a ΣΔ fractional-N PLL and some auxiliary circuits. The measurement result has demonstrated that the proposed transceiver can satisfy the dual-band requirements with comparable or even better performance in noise, receiver sensitivity and power consumption compared to previously-reported transceivers for only a single band.
