Novel Single Input Five Output Voltage Mode Universal Filter Based on DDCCTA

Abstract

A novel single input five output voltage mode universal filter based on differential difference current conveyor transconductance amplifier (DDCCTA) is presented. It employs grounded passive components namely two capacitors and a resistor. The proposed filter offers the following advantageous features: high input impedance-a desirable property of voltage mode filters; simultaneous availability of low pass, band pass, high pass, notch, and all pass; no matching constraint; low sensitivity performance and use of grounded capacitors suitable for integration. The effect of DDCCTA non-idealities on filter behaviour has also been addressed. The functionality of the design is verified through SPICE simulations using 0.25 μm TSMC CMOS technology.
