Although advances in photonics and electronics are making it easier and cheaper to implement a light detection and ranging (LIDAR) system, the analog front-end receiver interface still presents many ...

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 ...

Follow these seven steps to successfully select a photodiode sensor and design an analog front end for a range of applications such as optical communications and light-based measurements. The energy ...

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...

Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons. Photons of certain wavelengths, when absorbed by photodiodes, generate ...

The newly developed waveguide photodiode can be incorporated into various types of programmable photonic devices to measure the intensity of light travelling in the waveguide, with accuracy ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major ...

SI Sensors design novel CMOS image sensors for ultra-fast cameras that increase the velocity of the signal electrons allowing them to be swept out of the photodiode and be detected much faster.
