This is a compact three transistor, regenerative receiver with fixed feedback. It is similar in principle to the ZN414 radio IC which is now no longer available. The design is simple and sensitivity ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Microprocessors in smartphones, computers, and data centers process information by manipulating electrons through solid semiconductors, but our brains have a different system. They rely on the ...

Researchers previously reported a self-aligned technique for making graphene transistors with unparalleled speed, but scalability was a question. The team now uses a dielectrophoresis assembly ...

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 ...

Often, for certain low voltage lighting systems; you would like to turn off the lights during the bright light of the day. Most commercial day/night switches are designed for AC lighting. This hobby ...

Transistors are the fundamental building blocks behind today's electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...

At what age did you begin learning about electronics? What was the state of the art available to you at the time and what kinds of things were you building? For each reader these answers can be wildly ...
