Answer to Question #101107 in Electric Circuits for SAHIL

Question

HOW op amps can be used as an INDUCTOR ? prove it mathematically

Answer 1

For instance, two op-amps with resistances can be used to simulate an inductance. That circuit was developed by Andreas Antoniou and is shown below:

The equivalent inductance from this circuit is

$$L=\frac{R_7R_9R_10C_9}{R_8}.$$
