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 2D devices fabricated using CDimension’s ultra-thin films have demonstrated up to a 1,000X improvement in ...

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 ...

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 ...

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 ...

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 ...
