Serial powering is the baseline choice for low mass power distribution for the CMS and ATLAS HL-LHC pixel detectors. For this scheme, two 2.0A Shunt-LDO (SLDO) regulators are integrated in the RD53 prototype chip (65 nm) and are used to provide constant supply voltages to its power domains from a constant input current. System level simulation studies will be presented, in which a detailed...
A prototype second-stage buck DC-DC converter has been designed in 130nm CMOS and fully characterized. This circuit provides up to 3A at an adjustable output voltage of 0.6-1.5V from an intermediate bus voltage of 2.5V. Hardness by design techniques have been systematically used, and the prototype successfully passed TID irradiation up to more than 200Mrad and Single Event Effects tests with a...
