User:Constant314/Generalized Impedance Converter

A generalized impedance converter or GIC is a sub-circuit that can be used to implement an active impedance. Its applications include implementations of simulated inductors, gyrators, frequency dependent negative resistors, second order active filters and second order active filters with transmission zeroes. A variety of implementations exist. Temes describes four implementations, but notes that the different implementations have different stability properties. Chen and Wait  describe circuits based on state variable filters.

Wait gives the circuit shown to the right as suitable for a grounded FDNR.
