Electronically-controlled multifunctional current mode filter based on commercially available current conveyors and buffers

Application of commercially available modern functional blocks used for design of analog filters using integrator synthesis method is discussed in this paper. One example of all possible structures of 2nd-order multifunctional filters with current conveyors and followers is chosen and designed. Attention is paid to electronic control of parameters of the filter, sensitivity analysis and computer simulation using OrCAD.
