Abstract :
The realization of simple active filters in which the capacitors exhibit substantial dielectric loss is described. Accurate predictions of the filter voltage transfer function are possible by using a frequency-dependent model of the capacitor. The technique has been successfully applied to single- and dual-OA configurations
