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 ...

Imec, the nanoelectronics and digital technologies research hub, has announced the successful integration of a pinned photodiode structure into thin-film image sensors. With the addition of a ...

A photodiode also referred to as a photo-detector is a semiconductor device that converts light energy into an electrical current. Photodiodes are sensitive to light across a specific range of ...

This circuit was developed to aid manufactures of optical equipment in using linear detectors arrays with their optical setup without requiring specialised knowledge of electronics. These circuits ...

Editor’s note: This article will be in two parts. Part 1 is component-related and Part 2 is applications. Please also see Planet Analog blog “LEDs Are Photodiodes Too” as an intro to this article.
