Programmable photonics devices, which use light to perform complex computations, are emerging as a key area in integrated ...

What is a PIN avalanche photodiode (APD)? What is a PIN photodiode? How to characterize avalanche breakdown in GaN. Major differences exist between a PIN photodiode and an avalanche photodiode (APD), ...

Using a bootstrapping scheme with a JFET can enhance a photodiode’s ac response, but adds unwanted dc voltage. Remedy that problem with a matched dual-JFET. 1. This circuit uses a JFET to bootstrap ...

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 ...

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 ...

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 ...

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.

Silicon Carbide (SiC) integrated circuits are emerging as a critical technology in the development of electronics capable of reliable operation in extreme thermal environments. The unique material ...

Programmable photonics promises faster, more energy-efficient computing than electronics by transmitting signals using light.
