摘要

摘要:介绍了用于赫歇尔空间天文台(HSO，以前称为FIRST)光导体阵列相机和光谱仪(PACS)的冷CMOS读出通道的低温设计[1]。稳健的结构和优化的尺寸减少了低温异常对电路的影响。在室温和4 K下的仿真和测试结果表明，非线性< 2%，迟滞<5mV，噪声< 100nV/H~”~ @ 30Hz。

A 4.2 K readout channel in a standard 0.7 /spl mu/m CMOS process for a photoconductor array camera

Abstrsct:The cryogenic design of a cold CMOS readout channel to be used in the Photoconductor Array Camera and Spectrometer (PACS) aboard the Herschel Space Observatory (HSO, formerly called FIRST) [I], is presented. Robust architectures and optimized sizing reduce the effect of cryogenic anomalities on the circuit. Simulation results and tests, both at room temperature and 4 K show a non-linearity < 2%, a hysteresis of <5mV and noise < 100nV/H~”~ @ 30Hz.
