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 ...

In the half-century since the transistor was invented, this workhorse component of almost every electronic device has shrunk from the size of a pencil eraser to smaller than a bacterium. The ...

"The circuit is interconnected in such a way that only 22 control signals are needed in testing more than 2,000 nanotubes," said Yu-Chih Tseng, a UC Berkeley graduate student in electrical engineering ...

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

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 ...

The recent EDN article of Bruce Trump () on the input impedance of an op-amp circuit took into account the single-pole roll-off of its loop gain. He showed with a simple derivation how the equivalent ...
