Fast DEPFET read-out for the SIMBOL-X low energy detector

The new advancement in low-noise X-Ray detection paves the way to new space missions for deep space investigation, like SIMBOL-X. The concept of an APS (Active Pixel Sensor) based on DEPFET (Depleted P-channel FET) structure has been developed to cope with the emerging requirements. Although the use of DEPFET makes feasible to achieve the required noise performance, it is necessary to develop a suitable front-end ASIC to fulfill the challenging speed requirement.
