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 ...

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 ...

(Nanowerk News) Data transmission over long distances usually utilizes optical techniques via glass fibres – this ensures high speed transmission combined with low power dissipation of the signal. For ...

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 ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

(Nanowerk Spotlight) Transistors are the fundamental building blocks of modern electronic devices. Depending on whether they are used to amplify or switch electronic signals they can be grouped into ...

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 ...

Abstract: A low-noise amplifier for 4 GHz radio has been designed and is in manufacture. The noise figure is ≤2 dB and the gain is typically 10 dB. Input and output return losses are ≥25 dB. The ...

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 ...

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.
