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 ...

How to stabilize transimpedance amplifiers used to convert photodiode current output to voltage. Fig 1. Shown is a basic TIA circuit used in dual-supply systems. Fig 2. Figure 1’s TIA circuit ...

Researchers developed a single photodiode sensor that detects full-color light using perovskite materials, impedance data, and machine learning algorithms.

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 ...

A new quantum sensor for measuring photosynthetically active radiation (PAR) was designed using a gallium arsenide photodiode. This sensor is cheap and effectively measures radiation between 400 and ...

A G-M tube is not the only game in town though, and even the humble photodiode can be pressed into service. [Robert] gives us a good example, with a self-contained radiation detector head that ...

Introducing a new series of gain-stabilized Silicon Avalanche Photodiodes S15415, featuring a built-in temperature compensation function inside the chip. This feature enables a constant gain, ...
