This Design Idea is a two-wire current regulator that strikes a good balance between performance and parts count. Employing three transistors, three resistors, and one LED, it achieves good regulation ...

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 ...

For almost two decades, scientists have been trying to move beyond silicon, the material ...

The transistor has been around since the nineteen forties. In fact, the FET (Field Effect Transistor) was actually developed before the more common bipolar type. Bipolar transistors use semiconductor ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

To achieve the power, performance, and area (PPA) advantages dictated by Moore’s law, transistors have evolved substantially over the years. The development of planar transistors at Fairchild ...
