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.
The circuit presented was found in the 1994 Linear Applications Handbook from National...
This circuit, which in our times would be called a shield, can also be used with other loads. The...
This circuit is intended for amplification of signals in the range of 1.8 to 20 MHz. The...
