Paper Abstract

Silicon VLSI technology can be used to build a high density readout circuit for the emerging high resolution IRFPA imaging system. The readout circuit has to be operating at liquid nitrogen (LN) temperature in order to both improve system performance and design simplicity as well as reduce complexity. Devices with various sizes are measured down to LN temperature. As silicon MOSFETs cooled down, various anomalies are observed. The observed anomalies in the measured results are described and explained whenever possible. The two most important temperature dependent parameters -- threshold voltage and carrier mobility are studied. Simple guidelines are provided to obtain suitable SPICE MOS level 3 dc parameters for circuit simulation.
