Sub-project MEDACAL-SPHERE has two specific objectives within the coordinated project. Both objectives are connected among them. The first one is to contribute and support the measurements, calibration, and the interpretation of the data obtained from the MEDA wind sensor, which uses a mixed-signal ASIC designed using radiation hardening by design techniques and which performs the conditioning, acquisition and conversion of the sensor signals. This ASIC was developed by the research team in the framework of previous research projects (the MEDA wind-sensor ASIC). The second objective is the design, fabrication and validation of a new mixed-signal ASIC for a new generation of the wind sensor, the so called spherical wind sensor, developed like the previous one by the Polytechnic University of Catalonia. This new version of wind sensor, more accurate than the previous one, will be used as a reference element for the fine calibration of the MEDA wind sensor, which will be sent to Mars, therefore connecting with the first objective. As a result, this new ASIC,which constitutes the second objective, will have the double function of completing the development of the new generation of spherical wind sensors, and serve as a reference for the detailed calibration of the sensors sent to Mars in the framework of NASAs Mars2020.
