ABSTRACT:In this paper, design of a CMOS tunable versatile filter using current conveyor (CC) is presented. The filter is realized at the same time as on the chip is tunable for low pass, band pass, high pass, and elliptical notch filter. The circuit is utilizes two current conveyors, one Operational Trans-conductance Amplifier (OTA), four resistors and two grounded capacitors, ideal for integration. It has only one output terminal and the number of input terminals may be used. Further, there is no further requirement of component matching in the circuit.
