Abstract :
Software defined radio (SDR) becomes more and more popular due to the requirement of multi-standard communication. In the front end, the increasing demand for multi-mode wireless communication necessitates low cost, highly integrated and multi-bandwidth analog circuits to be implemented. This paper presents an overview on the consideration of intermediate frequency (IF) filter design for five communication standards: GSM, WCDMA, 802.11b, 802.11g and WiMAX. A transistor level multi-bandwidth IF gyrator-C filter is designed. Through the frequency response we can analyze the filter channel selection for different standards.
