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 ...

Building a photodetector that works across a range of applications does not have to be complicated. In this post, we will break down a universal design concept that is flexible, practical, and ready ...

A drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, the chilling outflow of energy from the device can be ...

Transimpedance amplifiers (TIAs) convert a current to a voltage. In many systems, this current comes from a photodiode. In order to test a TIA, it is best to drive the TIA with a current that emulates ...

(a) The schematic working mechanism of the integrated spectrometer. Conjugated-BIC photonics and combined waveguides are planarly integrated with perovskite photodiode arrays. Monochromatic light with ...

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 ...
