PIN Photodiode
-
PIN photodiode is a kind of photo detector, it can convert optical signals into electrical signals.This technology was invented in the latest of 1950's. There are three regions in this type of diode. There is a p-region an intrinsic region and an n-region. The p-region and n-region are comparatively heavily doped than the p-region and n-region of usual p-n diodes. The width of the intrinsic region should be larger than the space charge width of a normal p-n junction. The PIN photo diode operates with an applied reverse bias voltage and when the reverse bias is applied, the space charge region must cover the intrinsic region completely. Electron hole pairs are generated in the space charge region by photon absorption. The switching speed of frequency response of photo diode is inversely proportional to the life time. The switching speed can be enhanced by a small minority carrier lifetime. For the photo detector applications where the speed of response is important, the depletion region width should be made as large as possible for small minority carrier lifetime as a result the switch speed also increases.

UV Index Measurement
-
The sglux UV-Index sensors measure the UVI with a worldwide unique low measurement uncertainty of less than 5 %. This makes our sensors compliant to the highest measurement precisions class one according the DIN/EN 5031-11, chapter 8. Since 2018 our product UV-Cosine_UVI (ERYCA) is appointed for public authority tasks: The German Federal Office for Radiation Protection (BfS) services 27 measurement points in Germany for public information of the daily UV-Index. Twenty of these points (Andernach, Chieming, Duderstadt, Fichtelberg, Genthin, Giessen-Wettenberg, Schauenburg-Kassel, Langen, Lueneburg, Munchen-Neuherberg, Norderney, Belm/Osnabrueck, Schauinsland, Tholey, Todendorf, Waldhof-Falkenstein, Waldmuenchen, Wurmberg, Zingst and Zirchow) use the sglux ERYCA to obtain the local UV-Index value. In 2017 ARPANSA (Australian Government’s primary authority on radiation protection and nuclear safety) began replacing the existing biometers with SiC photodiode UV sensors (sglux ERYCA) at all network sites. There are currently thirteen measurement sites in Australia that have been upgraded to the new sensors.

Low Input Bias Current Amplifiers (<100 pA)
-
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.
