DVCC-Based Voltage-Mode Biquadratic Filter with High-Input Impedance

A high-input impedance voltage-mode universal biquadratic filter with one-input and five-outputs is presented. The proposed circuit uses three plus-type differential voltage current conveyors (DVCCs), two grounded capacitors and three resistors and offers the following features: the realization of a...

Description
Summary:A high-input impedance voltage-mode universal biquadratic filter with one-input and five-outputs is presented. The proposed circuit uses three plus-type differential voltage current conveyors (DVCCs), two grounded capacitors and three resistors and offers the following features: the realization of all the standard filter functions, that is, high-pass, band-pass, low-pass, notch, and all-pass filters, orthogonal control of omega o and Q, the use of only grounded capacitors, high-input impedance and low active and passive sensitivities.
