The transistor then switches on a second BC547, which lights an LED. The whole circuit is built on top of a battery clip so it can be run straight from the top of a standard 9 volt battery.

Current mirrors are just one more trick in the transistor magic hat. The real trick is applying them and combining them with other elements to get desired behavior.

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

This type of circuit is called optical smoke detector. Do not use it as a home smoke detector it’s jus for electronic projects. This causes the resistance of LDR to increase and the voltage at the ...

The sketch below shows a handy little circuit for keeping tabs on a high side current via an output signal that is ground referenced. With only two PNP transistors (2N2905 or similar) and four ...

That’s why it’s such big news that a team at Lawrence Berkeley National Laboratory has successfully built a functional 1 nanometer long transistor gate, which the lab claims is smallest ...

GaN Systems has unveiled its range of E-mode GaN-on-silicon high power transistors. Based on three core proprietary technologies, the GS65516T is said to boast the highest current capability on the ...

Researchers report a new, two-dimensional transistor made of graphene and molybdenum disulfide that needs less voltage and can handle more current than today's semiconductors.

Isolation amplifiers provide an effective method to protect IGBTs against over-current, overload and overvoltage conditions in addition to their current/voltage sensing function. Using these ...
