This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Photocouplers optically links, via transparent isolating material, a light emitter and a photodetector. Used as an interface between circuits with different ground potentials, photocouplers replace ...

The basic rules by which chips are being designed could be wrong, physicists have warned. Researchers at the US National Institute of Science and Technology have warned that a flaw exists in ...

Researchers at the University of Alberta are reporting a breakthrough in the development of molecular transistors, devices that function on the atomic scale and could lead to a quantum leap in ...
