摘要：
A current processing filter with two transfer functions (bandpass and notch/allpass) directly available is described. It uses a first generation current conveyor and six passive components. It is demonstrated that the choice of the passive component values leads to low passive and active sensitivities. The frequency, f0, and the quality factor, Q, can be chosen independently as regards the notch/allpass configuration. Simulation results made with SPICE confirm the theoretical analysis and are given and discussed. © 1990, The Institution of Electrical Engineers. All rights reserved.
