| Zusammenfassung: | A feedforward configuration for realizing second-order voltage-mode allpass transfer functions with complex poles using voltage-mode op-amps is converted to a feedforward current-mode scheme for the realization of second-order current-mode allpass transfer functions with complex poles using current conveyors. The scheme is capable of generating many different realizations for allpass transfer functions. Several new realizations are presented, and the effects of parasitic elements associated with the current conveyors in one realization are analyzed in detail. Simulations and laboratory measurements are provided. |
