This circuit was obtained in an old European publication on FETs. The FET admits equivalent and the feed must have good filtration. Signal input cables and output cables must be shielded.
In this circuit of a 1975 publication, a silicon transistor is used as a sensor. We can employ a...
This circuit was found in a 1978 publication. Equivalent operational amplifiers can be used. The...
The great advantage of the circuit shown in the figure is the fact that its frequency is...
