  1. ABC130 Submission F.Anghinolfi ABC130 ITk Meeting

  2. ABC130 Status • What has happened since the review (3 months ago) • The FrontEnd has shown a tendancy to instability when simulated with all channels active (detector signal on 240 channels) and inductances of wire bonds • The FE layout has been corrected : • specific power bus for the input branch of the preamplifier • Input to Calibration line shielding (was responsible for excessive crosstalk) • The regulators have been changed : • A more stable version has been installed that has 2 drawbacks : 1. Drop Out voltage is 0.3V worst case 2. Switch off residual current of a few mA (cannot be set to zero) ABC130 ITk Meeting

  3. ABC130 Status Before FE + regulator corrections ABC130 ITk Meeting

  4. ABC130 Status Before FE + regulator corrections ABC130 ITk Meeting

  5. Post extracted simulation with regulator (240 channels hit, Lv=1nH, Lg=0.5nH, cdec=0, Li=5nH, Lbck=5nH) After FE + regulator corrections Stable and clean. ABC130 ITk Meeting

  6. Post extracted simulation with regulator (240 channels hit, Lv=3nH, Lg=3nH, cdec=0, Li=5nH, Lbck=5nH) After FE + regulator corrections Stable and clean. ABC130 ITk Meeting

  7. ABC130 Status • Submission Preparation • Layout fixed without the FCF block • DRC almost clean (last corrections are manual) • LVS has still to be cleaned (was clean at a time but there were corrections of the FE and regulators) • Timing is built correct in the digital section by the PNR tool (and up to now verifications have shown correct functionality with timing and backannotation) ABC130 ITk Meeting

  8. ABC130 Submission on … • Shared Engineering Run (ABC + TDCpix) • ABC : Shared Engineering run with the NA62/TDCpix submission (forecast 1Q 2013) • Additional Eng. Run wafers at 3.6KUSD each (120chips/w) • Needs Synchro btw TDCpix(NA62) and ABC ABC130 ITk Meeting

  9. ABC130 Submission Scenario 2 • Shared Engineering Run (ABC + TDCpix) Additional Eng. Run wafers at 3.5KUSD each (120chips/w) Production Run wafers at 2.5KUSD each (120chips/w) 6.8x7.9 122KUSD ABC130 ITk Meeting

  10. ABC130 Submission Scenario 2 • Shared Engineering Run (ABC + TDCpix) Eng. Run + 1 Production run = 3720 chips Eng. Run + 2Production run = 6120 chips Eng. Run + 3 Production run = 8520 chips 6.8x7.9 ABC130 ITk Meeting
