On design of active notch tunable filter using multilayer uniformly distributed RC line

Abstract

This paper to design a novel technique for notch filter by using multilayer uniformly distributed RC line (MURC) with three capacitive layers is presented. The proposed circuit configuration consists of one notch characteristics circuit using MURC, one capacitor (Co) and a single gain amplifier. α1, α2, β and K parameters of the circuits are used to improve the magnitude response with notch tunable frequency. This structure reduces an amount of circuit complexity and is simple to use for applications. The experimental results and computer simulation showed good agreement with theoretical values and sensitivities are also carried out. ©2009 IEEE.
