Abstract
This paper explores the possibility of using the MASH (multi-stage noise shaping) technique in incremental converters to be used for x-rays detection, targeting a medium-high resolution in a limited conversion time. The presented 2+1 MASH receives at the input a current generated by a photodiode. The adopted scheme is hybrid as the input stage is continuous time while the remaining portion of the circuit operates at discrete time. The converter is studied at the behavioural level in the MATLAB-Simulink environment and some design trade-offs are analysed and discussed in details.
