Lossless inductor using current feedback amplifier

A lossless grounded inductor simulation scheme using the current feedback amplifier (CFA) device is proposed. The circuit configuration is a minimal $RC realisation that exhibits extremely low active sensitivity. The effects of the port tracking errors (/spl epsiv//sub t,v,t/) on the circuit parameters have been examined, and, subsequently compensation design equations have been derived. Tuning of this inductor by a capacitor across the driving point port yields a LC bandpass filter characteristics and self-oscillatory sinusoidal response (Q /spl rarr/ /spl infin/) which had been experimentally verified by hardware design and PSPICE macromodel simulation.
