An international group of researchers has developed an electronic device that is said to effectively mitigate hotspots in PV modules. It uses two current comparators, two NPN transistors, and a ...

Circuit and system design requirements often mean compromises. For example, optoisolators are used almost everywhere, but they are highfrequency limited. This simple circuit allows for wider bandwidth ...

The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

For applications that require or desire a computer controlled variable current, the use of a digitally controlled potentiometer and a current mirror with degeneration provides a low cost solution. One ...

Power monitoring systems require current sensing and are typically adjacent to, associated with, or integrated with hot swap controllers in server systems. Many designers have expressed a desire to ...
