Loss-compensated active gyrator using differential-input operational amplifiers
Andrew Prescott · Electronics Letters · 1966
A method of simulating grounded or floating inductance is described, which is dependent on invertor action associated with a well known T-π transformation, and which uses differential-input amplifiers. The circuit has been used as an oscillator, in low-frequency bandpass and low-pass filters, and also for simulating second-order transfer functions.
