Abstract

A new biquadratic universal filter configuration realizing second-order low-pass, band-pass, and high-pass fiters using single current conveyor is proposed. Using this configuration high-pass, low-pass and band-pass fiters can be realized with little modifications. The circuit employs a second-generation current conveyor (CCII+), and only four passive components. Since the current conveyor is a high performance active element, the circuit proposed is suitable for wide band applications. The derived filters can be easily cascaded and use reduced number of passive components compared to previously reported counterparts. To illustrate the design possibilities provided by the introduced circuit current mode multifunction filters are constructed and tested.
