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.

1154A -
Audio Authority Corp.
Consumers who own a receiver and/or TV with limited inputs can use the 1154A to add multiple A/V sources. Its exclusive Adaptive Signal SensingTM technology uses multiple criteria to decide when to switch sources, and adapts to users’ activity patterns, customizing its switching behavior over time. The high bandwidth circuitry accepts HDTV component video (YPbPr), stereo analog audio, and digital audio in both optical and coaxial formats, and switches all audio and video signals simultaneously when a new source becomes active. Digital audio signals are converted automatically to the desired format. Up to four sources may be connected to one receiver/video display system through the 1154A. A manual select button is provided to override the 1154A’s automatic selection. Multi-color front panel LEDs indicate source availability.
