The circuit was constructed around the functionality of a Class A amplifier to create a headphone circuit. BC308 – an epitaxial planar PNP transistor used for general purpose and low noise amplifier ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...

Immediately, I learned that the common base configuration gain was 6db lower than the common emitter. This blew my mind. Then I started checking input resistance and was shocked at how low it measured ...

Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

(Nanowerk Spotlight) Transistors are the fundamental building blocks of modern electronic devices. Depending on whether they are used to amplify or switch electronic signals they can be grouped into ...
