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 ...

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 ...

Abstract: Transimpedance amplifiers (TIAs) are widely used to translate the current output of sensors like photodiode-to-voltage signals, since many circuits and instruments can only accept voltage ...

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 ...
