Recently the input impedance of a differential amplifier was derived and discussed. This correspondence derives similar results using a different approach, namely, Blackman's impedance relation, and generalizes earlier observations. The results provide an alternative active RC realization of a bilinear RL impedance. Various all-pass networks are also analyzed.
