Abstract
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) [1], 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/Hz
1/2
@ 30Hz.
