None of the previously reported voltage-mode universal biquad filters with three inputs and a single output offers either of the following two important advantages: (i) the use of only one active element and (ii) independent control of ω0 and ω0/Q. In this paper, a novel biquad filter, achieving both of these advantages, is presented. HSPICE simulation results using TSMC025 process and ±1.25 V supply voltages validate the theoretical predictions.
