In no particular order of priority: 1) Vary ASIC V_DD=3.3V within +/-10% operating range 2) Use 'clean' floating high voltage detector bias - check polarity - is there a difference between detector local ground on p+n junction or n+n ohmic sides of DSSSD? - common or isolated detector local ground for multiple DSSSDs? - RFQ submitted for 1x CAEN N1419 - additional filtering for Emco Q05-5? - other? 3) Backtrack changes to date - Kapton PCB mods - PSU set points - Standard FEE64 PSUs -> linearly regulated PSUs 4) Evaluate effect of ASIC parameters 'Ibias preamp SF' and 'Ibias preamp' on noise 5) Evaluate effect of ASIC parameter 'preAmp reference' on stability of positive and negative input configurations Comments and corrections welcome!
