New high-Q band-pass filter configuration using current controlled current conveyor based all-pass filters

New first-order canonical current processing all-pass filters based on current controlled current conveyors are proposed. The proposed first-order allpass sections employ only a single active element and a bare minimum number of passive components. Both of the time constant and the all-pass conditions of these filters can be electronically adjusted. As an application of the proposed first-order all-pass networks, a new high-Q band-pass filter, which offers a number of advantages over their counterparts, is also given
