Active DURC notch filter

Abstract

This article present to voltage mode active notch filter using double capacitive layers uniformly distributed RC line (DURC) with the proposed active notch filter circuit configuration consists of one DURC, one resistance(Rn). and a DC voltage gain amplifier. The parameters of the proposed circuit such as; α, β and K are adjustable the frequency responses with notch tunable frequency. The experimental and simulation results by MATLAB and PSPICE are showed god agreement with the theoretical.
