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 ...

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 ...

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 ...

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 ...

In analog layout design, precise layout matching techniques are crucial to ensure the accuracy and performance of the circuit so that transistors exhibit similar electrical properties (i.e.

The mirror mechanism is the mechanism that unifies perception and action, transforming sensory representations of the behaviour of others into motor representations of the same behaviour in the brain ...
