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 ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of ...

All operational amplifier (op-amp) datasheets have an input voltage range limitation called the common-mode range. Strictly speaking, the common-mode voltage is the average voltage on the two inputs ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

The goal of this series is to maximize the voltage gain of the single transistor amplifier. I had always thought that hFE had a profound effect upon voltage gain, so I set out to determine how ...

Research that capitalizes on the wide-ranging capabilities of graphene could lead to circuit applications that are far more compact and versatile than what is now feasible with silicon-based ...

There appears to be 16 large transisitors which were mounted to the heatsink of this amplifier. It is a Planet Audio 4 channel car audio amp. From some quick Google searching, it looks like I should ...

Amplitech announces the deployment of its proprietary low-noise cryogenic High Electron Mobility Transistor amplifiers. The company has delivered these amplifiers to two Fortune 50 companies, ...
