Using current mirror for current sensing in high current MOSFET applications significantly reduces power loss in current sensing circuit and lowers design cost by replacing expensive high power ...

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 ...

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 ...

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 ...

This file type includes high resolution graphics and schematics when applicable. In some situations, it becomes necessary to drive a MOSFET (or IGBT) with a voltage that’s lower than its ...
