If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

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 ...

A research group succeeded in developing the world's thinnest and lightest differential amplifier for bioinstrumentation. Conventionally, bioinstrumentation circuits for health care and medical use ...

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 ...

This is an excerpt from “Self on Audio,” by Douglas Self, used with permission from Newnes Publishers, a division of Elsevier. For many years I felt that the output stages of power amplifiers ...

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 research group in this study developed the world’s thinnest and lightest signal amplifier for bioinstrumentation and demonstrated high-precision monitoring of electrocardiac signals with reduced ...
