The main activity of CERN (the European Organization for Nuclear Research) consists of collecting and analysing data generated from high energy particle colli- sions to study the fundamental constituents of matter and their interactions. This is done by using sophisticated particle detectors that include various electronic cir- cuits. As any electronic system, efficient power delivery to the detector is crucial. However, extra requirements are imposed by the highly radioactive environment, where radiation doses can reach 1 Grad of Total Ionizing Dose (TID) across the lifetime of the circuit. The lack of commercial solutions necessitates the design of radiation-hard power circuits such as DC-DC converters in order to properly operate in such environment.
