If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

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 ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

Bipolar junction transistors transfera current from a lower-resistanceemitter to a higher-resistance collector.You can use this property to measureinductance by ...

Learn how to build a DIY portable speaker using a car speaker, cardboard, and basic electronic components. This step-by-step ...

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 ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...

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 ...

Downscaling of electronic devices, such as transistors, has reached a plateau, posing challenges for semiconductor fabrication. However, a research team led by materials scientists recently discovered ...
