Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...
A Planet Analog article, “ 2N3904: Why use a 60-year-old transistor? ” by Bill Schweber, inspired some interest in this old ...
Bipolar junction transistors transfera current from a lower-resistanceemitter to a higher-resistance collector.You can use this property to measureinductance by ...
[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 cheap ...

What Is a Transistor, and How Does It Work?
Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...
As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...
Analog circuit design using MOS transistors represents a dynamic and rapidly evolving field that is integral to modern electronics. Exploiting the inherent advantages of MOS technology—such as ...
MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable ...
The telephone company had problems with vacuum tubes, too, and hoped to find something else to use for switching telephone calls. The idea of somehow using semiconductors (solid materials such as ...
