A low power 14-bit 1MS/s extended-range incremental ADC for high energy Physics experiments in 28nm technology

This paper presents a 14-bit 1MS/s extended range incremental A/D converter composed by the cascade of two resettable second-order sigma-delta modulators in 28nm technology. The system is designed for applications in instrumentation electronics for particle physics. Design of the converter is reported, including feasibility study and switched capacitor implementation. Architecture simulation results including non-idealities are reported. The developed A/D converter will be used for ultra-scaled technology (28nm) radiation hardness study in high energy physics experiments.
