This circuit for currents from 500 mA to 1.5 A was found on a Ham Radio from the 90s. R4 determines the current in the load under test. Transistors must be equipped with radiators.
This adjustable circuit from 0 to 200 nA was found in a 90's EDN. The components can still be...
We found this circuit in a technical documentation from the 70s. The MC1555 is nothing more than...
Based on common operational amplifiers, this circuit was found in Texas Instruments documentation. The power...
