The circuit was designed to create a detection scheme with reference to light energy sources. Photo Detector – a device that detects and senses light and radiant energy which uses the principle of ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

In this section we shall discuss the interface between a photosensor and its associated electronics. There are really just two photocell applications – light measurement, and the reception of ...

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 ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

Silicon Carbide (SiC) integrated circuits are emerging as a critical technology in the development of electronics capable of reliable operation in extreme thermal environments. The unique material ...
