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.
