We report high gain, high sensitivity 1064-1550 nm avalanche photodiodes (APDs) that are capable of single photon counting in the linear mode below the breakdown voltage and at room temperature. Epitaxial Technologies has developed AIInAs/GaInAs APDs

Noise due to back-gate forward bias between substrate and source of a MOSFET is analyzed and simulated. Noise level is compared between two CMOS circuits with and without back-gate forward bias. It is found that the output noise introduced by the bac

The NICMOS3 infrared focal plane array (FPA), which was designed as a Hubble Telescope upgrade device, provides excellent low-noise images in the 1 - 2.5 micrometers (SWIR) band. Both the detector array and the readout multiplexer of this hybrid FPA

The NOAO's 8-m IR optimized telescope for Mauna Kea and NASA's SIRTF show that from 1 to 200 microns there are a number of unfulfilled needs in readout electronics. These include: extremely low readnoise, less than 10 electrons, stable operation at t

SUMMARYSchottky- barrier focal plane arrays are the only infrared imagers that are fabricatedby the well established silicon VLSI process. Therefore, at the present time they repre-sent the most mature technology for large -area high- density focal p
