Modeling of a gyrator circuit

By assuming a typical range of amplifier specifications, a model is derived for a capacitively terminated operational-amplifier Rgyrator circuit. Amplifier imperfections such as finite input and output resistances and also finite frequency-dependent amplifications are taken into account. The validity of the model is confirmed by using an exact computer-aided analysis and also by experiment. The model clearly shows the influence of each amplifier imperfection on the performance of the gyrator circuit, and it should prove useful to the network designer.
