CCII-Based Inverse Active Filters with Grounded Passive Components

Abstract

This paper introduces IAFs (inverse active filters) employing CCIIs (second generation current conveyors) and grounded passive components. The IAFs enable ILP (inverse low-pass), IBP (inverse band-pass) and IHP (inverse high-pass) characteristics by adding the circuit currents. Additionally, the circuit parameters ω0 and Q can be set orthogonally adjusting the circuit components. The achievement example is given together with simulation results by PSPICE.
