Two configurations for second order bandpass filters with current transfers are introduced. The circuits, which exhibit reduced values for the active and passive insensitivities, only use four passive components and necessitate two current conveyors. SPICE simulated results, which confirm the theoretical analysis, are given and discussed for current conveyors implemented in a translinear form.<<ETX>>
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 f/sub 0/, and the quality factor, Q, can be chosen independently as regards the notch/allpass...
