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.

A new electronically tunable current-mode sinusoidal oscillator with three quadrature outputs is presented. The proposed circuit employs three translinear conveyors and two grounded capacitors to realize three quadrature outputs with independent frequency control. The circuit requires no resistors and the frequency of the oscillator can be varied over a(More)
