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 ...

75 years ago this month, research scientists working at Bell Labs first created, then unveiled to the world a new device—the point contact transistor. Some call it the greatest invention of the 20th ...

Editor's Note: The following tutorial is one of a series of six on transistor theory by Howard Skolnik, retired Burr-Brown designer. In Part 1 of this series we explored the terminal impedances of a ...

Just as the common emitter amplifier and common base amplifier each tied those respective transistor terminals to a fixed potential and used the other two terminals as amplifier input and output, so ...

As of Dec. 23, 2017, the transistor was officially 70 years old. The invention of the transistor may have been the greatest technology development of the 20 th century. It has given us the integrated ...

A joint research team led by Professors Donghee Son and Jin-Hong Park at SKKU has developed a stretchable, self-healing, and reconfigurable electronic circuit platform that can autonomously recover ...

The concept of negative resistance has always fascinated me. Of course, a true negative resistance is not possible, and what is meant is a negative differential resistance (NDR). But of course knowing ...

In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...
