  1. LHCb Upgrade Electronics Meetings in 2012 (Thursday, 2pm): 13th December http://lhcb-elec.web.cern.ch/lhcb-elec/html/upgrade.htm Mailing list: Go to simba.cern.ch, search for lhcb-upgrade-electronics LHCb electronics, 11th October 2012

  2. News • Recent TWEPP workshop. • Many interesting & relevant talks/posters: • http://www.physics.ox.ac.uk/twepp12/index.asp • Next year: Perugia, Italy • SLVS/LVDS (GBTX signalling) • Do any sub-detectors require SLVS/LVDS translators? LHCb electronics, 11th October 2012

  3. DC-DC convertor DC-DC convertor (reminder: ST linear regulator no longer available) R&D nearly finished Pre-production can start in 2013 LHCb must define its needs Negative voltage version in development Some sub-detectors already testing, others not started IMPORTANT POINT: switching convertor: noise?!?! LHCb electronics, 11th October 2012

  4. V i n H i g h s i d e C o n t r o l V o u t P h a s e C i r c u i t C o u t L o w s i d e g n d From Stefano Michelis DC/DC ASIC LHCb electronics, 11th October 2012

  5. DC-DC parameters to define • Input voltage (maximum 10V) • Output voltage (Vout = 1.2 – 3.3V) • Output current (Iout <= 3A) • Radiation & B-field environment • Volume/mass constraints • Number of parts • Delivery timescale LHCb electronics, 11th October 2012
