Funding for the research activities carried out at IMSE-CNM comes primarily from the participation in competitive tender processes. The research is then conducted out via agreements, projects and contracts with national and international public organizations and private companies and organizations.

High-Speed and High-Voltage ASICs for Extreme Radiation and Temperature Enviroments
PI: Diego Vázquez García de la Vega
Type: Research project
Reference: RTI2018-099825-B-C32
Funding Body: Ministerio de Ciencia, Innovación y Universidades
Start date: 01/01/2019

Abstract: This project (ASICs-AVATART) supposes a necessary and important technological activity of development of mixed signal ASICs for space applications. This activity was started in 2008 within the framework of the MetNet mission and resulted in the creation of a group at the Microelectronics Institute of Seville/University of Seville, which has since them specialized in this type of designs. Thanks to this effort, it has been possible to respond, for example, to the need arising within the framework of the aforementioned MEDA station (to condition the signal of its wind sensors) and the possibility of making recurrent systems more and more compact (less weight, volume, consumption, etc.) as the ASIC-SIS20 for solar irradiance sensors (InMars). It should be noted that IMSE/US has its own RHBD library in AMS 0.35µm technology, with designs that have been shown to operate at temperatures of -126°C, and that also has experience in designs for space with other technologies and libraries (IMEC-DARE in UMC 180 nm, SOI-XFAB).
It should be noted that the development of mixed-signal ASICs for space use is identified in H2020 as a strategic line for Europe and nondependence. This project aims to advance in the line of Integrated Circuits for radiation environments and with the particularity of very low temperatures. Specifically, the project focuses on High Voltage and High Speed cases. Although there are works in this regard, the particularity of the present project is that it is intended that the circuits work at very low temperatures without having to be heated to accommodate the operating situation to the typical industrial temperature ranges for which they are usually characterized. On the other hand, the high speed and / or high voltage features usually require different technologies, which is why this project seeks to integrate them into the same package by exploring the multi-die techniques. Of course, these techniques must also be adapted to operate at very low temperatures without the need for heating. In the end, this project aims to provide increasingly compact solutions that are equipped with added values such as reliability and re-usability.

Abstract: This Project (ASIC-SIS) represents a very important technology activity for the development of a Mixed-Signal ASIC for special applications in the Mars surface. This activity started years ago (2008) in the context of the MetNet mission and give as a result the creation of a research group in the IMSE-CNM/University of Seville specialized in this kind of designs. Thanks to these efforts, it was possible to provide solutions to the needs of signal conditioning and compaction of wind sensors for the MEDA station.
It should be mentioned that the development of Mixed-Signal ASICs for space use has been identified in H200 as a strategic line for Europe and the not dependence. This project follows this line intending the development of an ASIC to support future and even more compact Solar Irradiation Sensors (SIS) that are being recursively used for surface mission in Mars (SIS are present in 4 missions: MetNet, EXM'16, EXM'18 y Mars2020); it demonstrates the large interest of this kind of systems. So, the project aims the maximum compaction as possible of the SIS but also providing added values of reliability and re-usability as well as incrementing its scientific potential to become a reference sensor at international level for future missions.
Namely, the global ASIC-SIS objective is the development of a Mixed-Signal CMOS ASIC for the advanced Solar Irradiation Sensor (SIS). It contemplates all the required phases or steps: definition of specifications and/or requirements, synthesis at different levels (architectural, circuits blocks, devices, etc.), fabrication, validation, qualification, etc., AII the work concerning the design of the ASIC will be carried out by the US but in collaboration with INTA, who will give the necessary support in the specifications and requirements during the different validation steps. Finally, the US will give to INTA the support to perform the validations of a compact SIS prototype including the ASIC.
