Hi Guys
In wikipedia gyrator, they use a amplifer to replace the gyrator. They claimed the attached circuit are equivilent.
First, I can not equal these two circuits.
Second, even they can equal, how does it relative to the gyrator idea? In other words, how can a op-am function as a gyrator? Normaly you use two for OTA with a capacitor to get inductance. I do not understand here how one op-am can replace four OTA.
Thanks a lot
