Final Report Abstract

Until September 2013 the fundamental and basic circuit workpackages of AP 1, AP 2, AP 3 and AP4 were worked on and have been described in the preliminary report. Practical applications were then designed in AP 5. Circuits and partially layouts were prepared to simulate and thus verify the circuit concepts, as well as to manufacture a chip in order to validate the practical usability. Within the project, we could - derive equation based design approaches for HV circuitry in LV CMOS - develop design wrappers to generate safe operating area checks in any technology design kit - derive sub-circuits with the capability of working on elevated higher supply voltages in a modern 65nm low voltage CMOS technology - successfully implement circuits mostly for power management applications.
