Abstract The RD53 collaboration has since 2013 developed new hybrid pixel detector chips with 50 × μm 2 pixels for the HL-LHC upgrades of ATLAS and CMS experiments at CERN. A common architecture, design verification framework been to enable final different sizes be designed, verified tested handle extreme hit rates 3 GHz/cm (up 12 GHz per chip) together an increased trigger rate 1 MHz efficient readout up 5.12 Gbits/s chip. Tolerance extremely hostile radiation environment Grad over 10 years...
Abstract The hfrh-buck (high frequency radiation hardened-buck) is a hardened DC/DC-converter operating at high switching of 100 MHz with small air core inductor 22 nH. To ensure dose, the circuit designed transistors 65 nm TSMC technology. By stacking power stage, converter can be supplied voltage up to 4.8 V. Stable operation achieved an output 1.2 V maximum load current 1 A. prototype demonstrates ability parallel connected hybrid-pixel modules in innermost layers.

The Shunt-LDO regulator has been integrated in the ATLAS and CMS pixel detector RD53 front-end chip to implement serial powering scheme which both experiments have chosen as baseline option for HL-LHC upgrade. performance of regulators characterized specific design challenges identified are related layout parasitics shallow trench isolation (STI) stress effects. In addition functionality circuits address crucial system level aspects like protection against overvoltage/overload verified.
