Abstract
Horowitz´s active RC synthesis procedure with a voltage controlled current source is combined with Sheingold´s realization of the active element using a differential-input operational amplifier to derive a circuit for an all-pass filter of any arbitrary order, having poles confined to the negative real axis only. Illustrative examples are worked out for the first- and second-order cases.
