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 ...

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 ...

You know the “just add a transistor” drill by now: a performance or functionality requirement comes up that you can’t support entirely using the blocks built into your favorite mixed-signal ...
