Voltage sag is a temporary drop in RMS voltage levels in electrical systems, usually caused by faults, motor startups, or ...

High-speed current sensing presents a designer with some significant challenges. Most techniques for sensing current involve measuring the differential voltage the current produces as it flows through ...

This video explains what a diode is and how it controls the direction of current in electronic circuits. Diodes allow current ...

I need a circuit to limit the voltage across some dissipation limited devices. It must: limit the voltage to a maximum of 1.5 V, have symmetrical limiting, be capable of accepting a current of 2 A, ...

BUFFALO, N.Y. — University at Buffalo researchers are reporting a new, two-dimensional transistor made of graphene and the compound molybdenum disulfide that could help usher in a new era of computing ...

The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current sink’s ...

To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach ...

Researchers report a new, two-dimensional transistor made of graphene and molybdenum disulfide that needs less voltage and can handle more current than today's semiconductors. University at Buffalo ...
