Abstract

In this article, a universal nth-order current-mode filter employing electronically tunable second-generation current conveyors (ECCIIs) and grounded passive elements is proposed. As the current gain of the ECCII can be controlled electronically by adjusting the ratio of its DC bias currents, it is possible to tune all the coefficients of the transfer function independently. SPICE simulation results using TSMC 0.35m CMOS process model are included to verify the theory. Furthermore, a design example of a fourth-order video band filter is given to illustrate the application of the introduced topology in analog circuit design.
