This wide-range radiation monitor was found in a 1980s documentation. The circuit uses a diode as a sensor and is quite critical requiring shielding shown in dashes to prevent snoring due to gain.
In the figure we present an interesting application suggested by Microchip (www.microchip.com) in which the voltage...
This circuit was found in an English technical documentation from 1973. The circuit generates...
We found this circuit in a 1974 documentation. The NPN transistor can be the BD135 and the PNP the...
