This line is devoted to the development of integrated circuits and analog/mixed-signal systems for space applications, and in general, for applications in environments suffering radiation and extreme temperatures, with high reliability requirements. The use of conventional CMOS technologies is emphasized, following the concept of radiation hardening by design (RHBD).

Specific activities include the characterization of the effects of high-energy electromagnetic and particles radiation (total ionizing dose –TID, and single-event effects –SEE) on integrated circuit production technologies, on devices and circuits, and the development of robust strategies for the design of circuits and systems.

Other topics of interest include the tolerance of circuits to extended temperature ranges, and the resistance of packages and systems to thermal cycles, impacts, and vibration.

Accomplished tasks include:

• Characterization of a 0.35µm CMOS technology concerning radiation effects and extended temperature ranges.
• Development of radiation tolerant digital-cells libraries.
• Development of electrical models for the simulation of MOS transistors with specific radiation-hardened layouts (ELTs).
• Design and test of several mixed-signal ASICs for space use.
  - OWLS: intra-satellite optical communications based on diffuse light.
  - MOURA: tri-axial magnetometer and accelerometer.
  - MEDA: wind sensor for MEDA, for Mars'2020.
  - SIS: solar irradiance sensor for Exomars'18.
• Formal qualification processes for the space-use of mixed-signal ASICs.
