The handedness or “chirality” of electrons affects how current flows in graphene transistors, according to new work done by researchers in the UK and Russia. The team’s findings could help to make ...

Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...

This Design Idea is a two-wire current regulator that strikes a good balance between performance and parts count. Employing three transistors, three resistors, and one LED, it achieves good regulation ...

Transistors act as electrical switches. In the on position, which represents the “1” of binary digital information, a designated amount of current flows from one side of a semiconductor to the other.

Current sensing is used to perform two essential circuit functions. First, it measures “how much” current is flowing in a circuit; information that may be used for power management in a DC/DC power ...
