In many low-power applications such as USB adaptors, cell phone chargers, and system bias supplies, the low-cost quasi-resonant/discontinuous-mode flyback converter ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the first ...

Miniature self-sensing transistor thermostats use a single transistor (BJT or FET) to serve as both a temperature sensor and stabilizing heater. These transistor thermostats are (when well designed) ...

We all know that it’s easy to get caught out by fake electronic components these days, with everything from microcontrollers to specialized ASICs being fair game. More recently, retro components that ...

Transistors are no doubt one of humankinds greatest inventions. However, the associated greatness brings with it unprecedented complexity under the hood. To fully understand how a transistor works, ...

There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at Bell ...
