Light detection is important for many types of electronic instruments. One of the most important of these light detecting tools is the photodiode. These tools are present in dozens of electronic devices. Photodiodes are semi-conductors that convert light into electrical voltage. This turns light signals into electrical input instructions that the machine can understand. Infect photodiodes are optoelectronic devices, meaning that they create electricity when light shines on them, similar to photovoltaic cells. In this article a brief about photodiodes are discussed.The Himalayan Physics Vol. 4, No. 4, 2013 Page: 95-98 Uploaded date: 12/23/2013

The performance of Lu/sub 2(1-x)/Ce/sub 2x/(SiO/sub 4/)O (LSO) detectors was assessed under laboratory conditions. The PMT (photomultiplier tube) and the APD (avalanche photodiode) gave the same energy resolution when used with LSO, although the APD displayed a thermal noise threshold of 30 keV compared to <5 keV for the PMT. The PD resulted in a power energy resolution of 14% and also a considerably higher noise threshold of 140 keV. One notable advantage of LSO scintillators over CsI(Tl) and CdWO/sub 4/ when used with APD detectors is the short decay time of 40 ns. This allows the use of much shorter amplifier shaping times, 0.25 mu s for LSO compared to 3-20 mu s for CsI(Tl) of CdWO/sub 4/, which dramatically improves the count-rate capability of the detector as well as the ratio of signal to noise.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

The LMV301 CMOS operational amplifier can operate over a power supply range from 1.8 V to 5 V and has a quiescent current of less than 200 �A, maximum, making it ideal for portable battery−operated applications such as notebook computers, PDA’s and medical equipment. Low input bias current and high input impedance make it highly tolerant of high source−impedance signal−sources such as photodiodes and pH probes. In addition, the LMV301’s excellent rail−to−rail performance will enhance the signal−to−noise performance of any application together with an output stage capable of easily driving a 600 � resistive load and up to 1000 pF capacitive load. The LMV301 comes in the space saving 5−pin SC−70 package with an industry−standard pinout, giving it both equivalent function and similar performance to competitive devices. Features

The Silicon PIN photodiode (NR-PIN) with active area (3.5. x 3.5. mm 2 ) was designed and fabricated on (100) N-type floating zone silicon substrates by using conventional photolithography process at Nuclear Radiation Detectors Applications and Research Center (NRDAM). To get NR-PIN and BPW34 specifications, capacitancevoltage (C-V) and current -voltage (I-V) measurements were accomplished at room temperature by using Keithley 4200-SCS and results were compared. The leakage current and capacitance at -10V are 20 nA and 17.7 pF for NR-PIN, 32 nA and 27 pF for BPW34. Even if NR-PIN has good results at low reverse voltage, it is unstable at high reverse voltage compared to BPW34 photodiodes.
