Abstract
In the paper, the theory of pseudo-differential filters is examined and supported by designing a fourth-order frequency filter operating in current mode and implemented as cascade connection of two basic second-order blocks. The basic block employs three current conveyors as active elements and four passive elements. The filter is characterized by a high output impedance, and minimum number of passive elements, whereas capacitors are grounded. To prove the operability of the final filter, the partial second-order pseudo-differential filters were interconnected in four different ways. The simulation results of the each interconnection prove proper behavior of pseudo-differential filters in analogue signal processing.
