A CMOS radio receiver architecture for ISM/UNII multi-standard wireless applications

Various wireless communication standards have been introduced and multi-standard wireless devices are highly demanded to accommodate different wireless communication standards. Due to the different frequency bands and bandwidths, existing multi-standard wireless devices use separate chipsets or separate signal paths for the different standards on the same chip. Low and zero-IF receiver architectures with high integration and high level of component share are proposed for Bluetooth and WLAN applications. The overall system requirements are analyzed and the design specifications for individual receiver components are determined using a Simulink model. The system design is targeting implementation in deep submicron CMOS technology, e.g. the 0.18 μm process.
