A CMOS RF TUNING WIDE-BAND BANDPASS FILTER FOR WIRELESS APPLICATIONS

摘要

This paper presents a 4th order RF bandpass filter based on active inductor. In the filter, a design technique for a high-Q CMOS active inductor operating in the wide RF-band is described. Simulated performance is shown that the center frequency of filter using a 0.25-um CMOS process can be operated at the 1.81G～2.45GHz frequency band under a 1.8V power supply.
