An inductive synthesis circuit that mimics an ideal inductor over a wide range of inductance values, from less than 1 mH to more than 100 H, can be used in place of an inductor in any electrical circuit. One application of a synthesized inductor is in an integrated circuit in which it is impractical to construct a coil of wire. The inductive synthesis circuit is suitable for use in a calibration instrument for testing an inductance meter. The inductive synthesis circuit, together with a resistive synthesis circuit and a capacitive synthesis circuit, can be used to calibrate a multi-meter. Alternatively, the inductive synthesis circuit can be used to mimic an ideal inductor in a filter circuit that includes an inductor component, such as a high pass filter, a notch filter, or a band pass filter.
