High input impedance SIMO versatile biquad filter

Abstract

This paper presents a new Single Input Multiple Output (SIMO) versatile biquad Filter based on fully differential current conveyor (FDCCII). The filter uses grounded passive components suitable for monolithic implementation. The proposed circuit realizes all the standard filter functions in voltage and current form, that is, high-pass, band-pass, low-pass, notch, and all-pass filters simultaneously without changing the passive elements. PSPICE simulation results are given to verify the proposed circuit.
