Abstract
Ladder-based allpass filters are derived for active resistance-capacitance (RC), switched-capacitor (SC), and digital realizations. The resulting circuits have the properties of parallel structures and very low amplitude sensitivities. The implementations are canonical with respect to the number of opamps or delays and multipliers. Examples are given, and these are critically assessed for component spread and sensitivities
