Novel LC pseudo switched capacitor filter suited for wireless RF applications

Abstract : Switched capacitor filters have been in wide-spread used for a few years, for the realization of stable, accurate and high quality filters for operating frequencies below the megahertz range. This paper would like to prove the feasibility of a novel tuned LC pseudo switched capacitor filter with high quality factor of several hundreds for wireless radio frequency applications. The filter is designed with standard 0.35µm silicon BiCMOS technology. Experimental results at 442MHz switching frequency demonstrate interesting performances; the quality factor is equal to 316 for a frequency bandwidth equals to 1.4MHz.
