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 ...

This video explains how transistors work and how they are used to switch and amplify electrical signals in electronic ...

If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

The circuit below shows a 4-transistor utility amplifier suitable for a variety of projects including receivers, intercoms, microphones, telephone pick-up coils, and general audio monitoring. The ...

This audio amplifier circuit delivers up to 200 W of top-class quality for loudspeaker from 4 to 16 ohm. Operating voltage is between 24 and 36 V, max 5 A. The frequency response is from 20 to 20000 ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...

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 ...

IT is well known that changes in the d.c. characteristics of transistor amplifiers with temperature are particularly severe, and tend to limit the range over which these devices can operate. The d.c.

Ampleon has released the BLP05H9S500P LDMOS-based power amplifier transistor designed for use in industrial heating, defrosting, plasma lighting and medical applications. Operating at a frequency ...

Announced yesterday, researchers from Surrey and Cambridge universities and the National Research Institute in Rome have used thin-film source-gated transistor (SGT) to create compact analogue circuit ...
