Multifunction voltage-mode filter, employing minimum number of active and passive elements

Abstract

A second-order multifunction voltage-mode filter with three inputs and one output, is discussed. The filter uses a novel current conveyor called balanced dual input-dual output current conveyor and minimum number of passive elements. Also the filter does not require passive element matching. The parameters angular resonance frequency and quality factor can be adjusted by changing the values of the resistors orthogonally.
