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 ...

The 4-20 mA transmitters used in industrial current-control loops can be implemented as powered current sources, remote non-powered current sinks, or with several other I/O combinations. A useful ...

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 ...

If you've ever designed an RF oscillator, you've probably encountered squegging. Sometimes called "motor boating," squegging causes oscillators to start and stop at frequencies much lower than the ...

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 ...

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.
