"Active Realization Of A Negative Inductor"
S. A. BOCTOR · 2005
A generalized expression defining the input admittance of any single op.amp. active-RC network is formulated. It is used to synthesize an ideal negative inductor using only one capacitor and two resistors. Due to practical limitations, the quality' factor of the inductor is finite, but high. Also, an extra resistor has to be added to the network. However, the Q-factor can be made infinite at any one specific frequency.
