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 . . .

In order to test and characterize optical front end circuits, a controllable, high bandwidth, microamp-level current source is needed. However, most optocouplers on the market have large CTR variation ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Introduction Electricity powers many of the devices you use every day. Those devices are made up of circuits, ranging from very simple (such as a lamp with a single lightbulb) to very complex (such as ...

What Is A Semiconductor Gate? The gate electrode is a thin film of a conductive material deposited on top of an insulator layer in a transistor. The gate sits above a channel formed in the main body ...

The importance of current limiting. A flexible solution for adding current limiting. In some power-management applications, precise current limiting is required. This is necessary either to protect ...
