Abstract

In this paper a design of high-Q switched capacitor presented and simulated. This circuit, which can replace high-Q external passive filters, allows a high selectivity with a tunable center frequency range of 400 MHz [700-1100 MHz], with quality factor up than 1100. Implemented in 0.18 mum CMOS technology, this circuit is intended to be used for ultra high frequency (UHF) applications which requires a very high-Q characteristic.
