In view of the upgrade of the LHC experiments, we are developing custom DC/DC converters for a more efficient power distribution scheme. Two new prototypes (AMIS3 and AMIS4) have been integrated in ASICs in the selected 0.35um commercial high voltage technology that has been successfully tested for all radiation effects: TID, displacement damage and Single Event Burnout. While AMIS3...

The Shunt-LDO regulator is a new regulator concept which combines a shunt and a Low Drop-Out (LDO) regulator. Designed to match the needs of serially powered detector systems, it can also be used as a pure LDO regulator for general application in powering schemes requiring linear regulation. The flexibility of the design makes the Shunt-LDO a good candidate for use in the powering schemes...

The engineering challenges related to the supply of electrical power to future large scale detector systems are well documented. Two options remain under active study in our community, namely serial powering and the use of DC-DC convertors. Whilst clearly different in detail, both have the potential to increase the efficiency of the powering system. The ATLAS Upgrade Strip Tracker...
