Abstract
IEEE, Erik J. Pankratz , Student Member , IEEE, and Edgar Sánchez-Sinencio, Fellow, IEEE Abstract—This paper proposes a biquad design methodology and presents a baseband low-pass filter for wireless and wireline applications with reconfigurable frequency response (Cheby- shev/Inverse Chebyshev), selectable order (1st/3rd/5th), continu- ously tunable cutoff frequency (1–20 MHz), and adjustable power consumption (3–7.5 mW). A discrete capacitor array coarsely tunes the low-pass filter, and a novel C
