Single FDCCII-based tunable universal voltage-mode filter. (English) Zbl 1136.94331

Summary: 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 \(\omega_0\) and \(\omega_0/Q\). In this paper, a novel biquad filter, achieving both of these advantages, is presented. HSPICE simulation results using TSMC025 process and \(\pm 1.25\) V supply voltages validate the theoretical predictions.
