Nearly every piece of technology you use—from smartphones to computers—relies on one revolutionary component: the transistor.

Perovskites have received a lot of attention as semiconductor materials for solar cells because they’re efficient, inexpensive, and easy to make. But designing transistors, the fundamental component ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...
