Multi-function current-mode filters based on MOCCII

Guoxiang Zhang

Abstract

The paper presents a new multi-function current-mode second-order filtering circuit based on MOCCII. The circuit is constructed only by two MOCCIIs and four RC elements. It can realize low-pass, band-pass, high-pass, band-stop and all-pass filtering outputs at one time without elements matching. All the RC elements are grounded, and the sensitivities of the circuit are very low. Analysis of non-ideal characteristic of the filtering circuit and computer simulation to proposed circuit is presented.
