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 ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

This efficient MOSFET power audio amplifier based on IRF530, IRF9530 HEXFETs and BC550C NPN transistor provides about 18W into 8 Ω speakers and up to 30W into 4 Ω speakers with a total harmonic ...

How a paper substrate and biodegradable circuitry can be used for basic circuits. How the researchers fabricated and connected active and passive devices literally “on paper.” Details of their first, ...

The circuit was designed to produce high quality and powerful audio amplifier that would provide 60W-90W power output. MPSA43 – NPN high voltage transistor with low current and high voltage used for ...

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 ...

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 ...

Using a paper substrate and wax resist, plus conductive and non-conductive inks, researchers have developed a functional, biodegradable circuit and its carrier. How a paper substrate and biodegradable ...
