The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...

"The circuit is interconnected in such a way that only 22 control signals are needed in testing more than 2,000 nanotubes," said Yu-Chih Tseng, a UC Berkeley graduate student in electrical engineering ...

Explore a straightforward method to using just one transistor. This clever technique powers small devices with minimal components, making it an efficient and practical solution. Watch as the process ...

Amplification is a process of increasing the signal strength by increasing the amplitude of a given signal with out changing its characteristics. Here we will concentrate how transistor is used as ...

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 ...

[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 ...

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 ...

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it's a semiconductor, this material can control the flow of electricity in a circuit. But silicon has ...

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 ...

[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 ...
