Advantages of Photodiode Array
Preface All products are continuously being improved for better performance. Spectrometers have developed in many ways since the introduction of simple and moderately priced spectrophotometers which were commercially available from the mid 1950’s. 1 Such improvements have enabled SCINCO to manufacture PDA type UV-Vis. spectrophotometers. The scope and performance of conventional single channel ...
متن کاملCMOS Process Photodiode Memory
Demand for high-speed dynamic reconfiguration of a programmable device is increasing for raising the performance level of such devices. To support high-speed dynamic reconfiguration, optically reconfigurable gate arrays (ORGAs) have been developed. An ORGA consists of a holographic memory, a laser array, and an optically reconfigurable gate array VLSI. The holographic memory can store many conf...
متن کاملPhotodiode Characteristics and Applications
5 Silicon photodiodes are semiconductor devices responsive to highenergy particles and photons. Photodiodes operate by absorption of photons or charged particles and generate a flow of current in an external circuit, proportional to the incident power. Photodiodes can be used to detect the presence or absence of minute quantities of light and can be calibrated for extremely accurate measurement...
متن کاملModelling of High Quantum Efficiency Avalanche Photodiode
A model of a low noise high quantum efficiency n+np Germanium Photodiode utilizing ion implantation technique and subsequent drive-in diffusion in the n layer is presented. Numerical analysis is used to study the influence of junction depth and bulk concentration on the electric field profile and quantum efficiency. The performance of the device is theoretically treated especially at the wave-l...
متن کاملAvalanche photodiode A User Guide
Introduction Avalanche photodiode detectors (APD) have and will continue to be used in many diverse applications such as laser range finders, data communications or photon correlation studies. This paper discusses APD structures, critical performance parameter and excess noise factor. For low-light detection in the 200to 1150-nm range, the designer has three basic detector choices the silicon P...
