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 ...

Immediately, I learned that the common base configuration gain was 6db lower than the common emitter. This blew my mind. Then I started checking input resistance and was shocked at how low it measured ...

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 ...

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 ...

Back in the '60s, there was an intriguing circuit article titled "Starved-Circuit Amplifier" published in Popular Electronics magazine. It used a sharp cut-off pentode with a 3-MO load resistor and ...

What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out ...

Scientists have achieved a twentyfold amplification of single-photon signals with the help of an ultracold quantum gas. Data transmission over long distances usually utilizes optical techniques via ...

Some of the many low-dropout (LDO) regulators supplying voltage regulation for electronic systems are designed for low noise. For example, the IC in Figure 1 achieves an RMS noise voltage of about 115 ...

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 ...
