High performance voltage - mode multifunction filter with minimum component count

摘要

This paper presents a new second order multifunction filter using one active element, requiring only 'twelve' CMOS transistors, and four passive elements. The proposed circuit realizes voltage-mode low-pass, high-pass and band-pass functions with the advantages of minimum component count structure, high Q possibility, and high frequency potential. The proposed circuit is verified through PSPICE simulation results.
