A CMOS RF bandpass filter based on the active inductor

Abstract

This paper presents a 6th order RF bandpass filter using low-voltage based on active inductor. In the filter, a design technique for a high-Q CMOS active inductor operating in the RF-band is described. Simulated performance presented is shown that the center frequency of filter using a 0.25-mum CMOS process can be operated at the 2.05-2.45 GHz frequency band under a 1.8V power supply and suitable for multiband wireless applications and RF system on-chip
