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 researching my latest article I ran across this paper about a “robust” photodiode amplifier (pdf). I use the scare quotes on purpose, since the whole article seemed a little fishy to me. The author ...

Photodiodes are used in a wide variety of applications to transform light into a current or voltage. These range from solar cells to optical data networks, from precision instruments to chromatography ...

How transimpedance amplifiers are used in fiber-optic communications, laser rangefinders, and LiDAR systems. How avalanche photodiodes enhance TIA performance. Application-specific design and topology ...

Members can download this article in PDF format. The precision op amp plays a key role in analog and mixed-signal circuits. Applications extend from measuring large currents by amplifying the voltage ...
