Abstract
Ladder-based allpass filters are extended for active RLC , active RC , SC and digital realisations. The resulting circuits have the attractive properties of parallel structure and very low amplitude sensitivity to component changes. The analogue implementations are canonical with respect to the number of op amps and the digital ones are multiplier canonic. Detailed examples are given for SC designs and these are critically assessed for capacitance spread and sensitivity
