Abstract

Infrared detectors for astronomy application are supposed to work under cryogenic temperature due to lower dark current and readout noise. A prototype for infrared detector front electronics which can operate under cryogenic temperature is presented on this paper. Several commercial off-the-shelf (COTS) devices from different technologies were extensively characterized at as low as 4K including voltage reference, operational amplifier, ADC, MCU and etc.. The results demonstrate that AD8616 could perfectly work under 4K, Cortex-M4 ARM MCU operates well above roughly around 35K, AD7983 start to loss code at 180K and XFET reference ADR433 begin to show a significant voltage drop at 120K. The failure mechanism of COTS devices is also analyzed based on the cryogenic test results.
