We break down the essential component of modern electronics—the transistor. Transistors are the building blocks behind most ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a ...

Imagine for a moment a simple transistor circuit involving a single NPN transistor with its emitter grounded, its collector tied to the positive supply by a resistor, and a potentiometer between ...

Shrinking silicon transistors have reached their physical limits, but a team from the University of Tokyo is rewriting the ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object ...

Ever wondered how a simple transistor can power an entire computer and run complex code? Discover the amazing world of ...
