A High Input Impedance Multifunction Filter Using Grounded Capacitors
K. Pal and M.J. Nigam

A universal voltage mode second order filter with three inputs and one output employing four differential voltage current conveyors, two capacitors and three unmatched resistors is presented. The circuit can realize low pass, high pass, band pass, notch and all-pass functions. The circuit is superior to earlier circuits as it has high input impedance and uses grounded capacitors which makes it suitable for integration.
