Novel Grounded Capacitor All-Pass and Notch Filters Using Current Conveyors and Differential Amplifier
Three circuits each realizing second-order all-pass/notch filter transfer functions are reported. All circuits use grounded capacitors and are suitable for IC implementation. These circuits offer the advantages of high input impedance and low output impedance and are superior to all earlier realisations.
