Driving point inductance of a transistor with R.C. feedback

A well-known active R.C. circuit with a single transistor gives a reasonably high value of simulated inductance with high Q, at one of its ports. This circuit has been analysed in terms of two-port admittance parameters. It has led to a new design procedure for such a circuit, to realize given values of inductance and Q factor. A bandpass amplifier with such a simulated inductance has been designed and tested.
