This configuration makes use of currently uncommon components. In fact, we found it in documentation from the 70s. Equivalent operational amplifiers can be used.
This circuit was obtained in a 1975 documentation. The maximum frequency depends on the diodes and the...
Found in a 1990 Hobbyst Handbook this circuit has an output power of a few tens of watts and...
The circuit shown is a constant current source which allows the reading of resistors on a very low...
