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

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 ìm TSMC CMOS technology.
