Abstract

This paper presents a compact second-order bandpass filter developed by combining the well-known flipped voltage follower circuit as a transconductance network with two capacitors. Operated in the subthreshold region, the filter’s center frequency can be adjusted linearly by varying the bias current. Post-layout simulation using a 0.35-[Formula: see text]m CMOS process confirms the suitability of the proposed filter in low-voltage, low-power environment.
