[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...

A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...

Ever wondered how a solar-powered lamp powers an LED with just a single 1.2 V cell? A closer look reveals a clever single-transistor voltage converter circuit. Curious how a solar-powered lamp powers ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

Smallest transistor ever created with gate only 1 nanometer long For more than a decade, engineers have been eyeing the finish line in the race to shrink the size of components in integrated circuits.

A technical paper titled “Tunnel Junction-Enabled Monolithically Integrated GaN Micro-Light Emitting Transistor” was published by researchers at the Ohio State University and Sandia National ...

The history of the transistor and similar types. How transistors made an impact on the world. How grudges eventually subside. Transistors are simple electronic devices that boost or switch electrical ...
