[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 ...

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 ...

It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier ...

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 ...

Transistor Amplifiers, Dennis Feucht, Innovatia, 2016, ISBN: 9781682736265; $60 US. Transistor amplifier literature has existed for well over a half century. Why another book on an old subject? What ...

Transistors made modern electronics possible, from radios to smartphones. This video explains how they control current, act ...

New research from the WISE group (Wearable, Intelligent, Soft Electronics) at The University of Hong Kong (HKU-WISE) has ...

Flexible, hydrogel-based transistors that can host living cells point to a new class of bio-integrated electronics, blurring ...

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 ...
