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 ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

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 ...

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 ...

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

Graphene is a sheet of carbon atoms arrayed in a honeycomb pattern, just a single atom thick. It could be a better semiconductor than silicon -- if we could fashion it into ribbons 20 to 50 atoms wide ...
