The systematic design of multiple-loop feedback current-mode filters based on MOCCII

Chunhua Wang

Abstract

The paper presents a systematic method of designing nth-order MOCCII (second generation current conveyor with multiple outputs) filter with multiple-loop feedback. Various kinds of filter structures can be obtained by this method. The produced nth-order filter is constructed by n MOCCIIsand2nRCpassiveelements,andisintegratedconvenientlyfortheRCelementsaregrounded.Designexampleof4th_orderButterworthfilteranditscomputerPSPICEsimulationresultsarealsogiven.
