[Paulo] just tipped us about an Excel based high frequency transistor amplifier calculator he made. We’re guessing that some of our readers already are familiar with these class A amplifiers, commonly ...

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 ...

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

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 ...

There is so much to learn about the single-transistor amplifier, that this brief tutorial hardly scratches the surface. This discussion considers only the common-emitter configuration as applied to ...

(PhysOrg.com) -- Rice University 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 ...

If your transistor amplifier sounds like crap, it is your fault, not that of the transistors: it means your amplifier doesn't have enough head room for the desired volume or that it was just plain ...

Millions of guitar player can’t be wrong. Well over 80% of guitar amplifiers new and existing still use vacuum tubes. Based on my experience, that could really be over 90%. Nevertheless, most guitar ...

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 ...

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 ...
