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 ...

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 ...

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

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.

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 ...

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 ...

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 ...
