This circuit simulates the effect of an inductance. Equivalent operational amplifiers can be used, and the power supply must be symmetrical. The circuit is from a 90's Poptronics.
This simple operational amplifier tester was published in the November 1987 issue of Radio...
The traditional circuit was taken from a French magazine Radio Plans that no longer exists but can...
This configuration can be made based on other operational amplifiers. For other frequencies, the...
