Nth-ORDER ALLPASS FILTERS USING CURRENT CONVEYORS

Dalibor Biolek - Josef »ajka - Kamil Vrba - VŠclav Zeman

   A special cell with a general four-port second-kind zero-class current conveyor is presented. The use of this cell for high-order allpass filter design is described. Some two-port realizations using the universal current conveyor are derived. It is shown that the designed network can operate in three different modes. Simulation results illustrate the properties of the proposed filters.

Keywords: current conveyors, allpass filters, group-delay equilizers
