Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. However, ...

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 ...

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 ...

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 ...

A recently filed patent (Publication Number: US20230314495A1) describes a capacitance measurement circuit that includes an analog front-end circuit, a parasitic capacitor, an analog to digital ...
