Description
The paper describes the final characterization results of the MEDA-WS ASIC, which was described in a previous paper in AMICSA-2016. It describes as well the qualification and the screening processes that have been carried out, and the present status of its integration and calibration in the final engineering and flying modules of the wind-sensor instrument.
Specific details include to the low-temperature and radiation tests, the final packaging and its qualification implications, as well as some thermal behavior considerations.
The paper begins with a brief review of the ASIC description and functionality, as well as the circuit techniques employed for its different circuit blocks and the RHBD techniques used.
Although the ASIC fulfils the prescribed specs and accuracy figures, and will be used "as is" in the instruments to be sent to Mars, a few sources of minor accuracy deviations that have been identified will be described together with their eventual future correction in other versions of this or other similar ASICs.
Summary
The paper describes the final steps of development, characterization, screening, qualification and integration in the aimed instrument of the MEDA Wind-Sensor ASIC. This ASIC, whose design and preliminary functional measurements were already reported in AMICSA-2016, is a key component of the wind-sensor included in the MEDA instruments set for the upcoming Mars-2020 mission.
