Radiation characterization of the austriamicrosystems 0.35 µm CMOS technology

Abstract

The design of mixed-signal ASICs for space requires a detailed knowledge of the behaviour of the technology to be used in an environment imposing radiation levels and temperatures beyond those found in standard applications. Commercial foundries providing standard CMOS technologies do not usually have or make available data on the behaviour of their devices under those conditions. Instituto de Microelectrónica de Sevilla and Universidad de Sevilla (IMSE-USE) have started a long term collaboration with the Spanish Instituto Nacional de Técnica Aeroespacial (INTA) to extend its experience on mixed-signal design to the field of ASICs for space applications. The assessment of a commercial (austriamicrosystems) 0.35µm CMOS technology is a first step towards the development of a mixed-signal design methodology, including the development of an RHBD digital library suitable for use in space conditions.

A rad-hard multichannel front-end readout ASIC for space applications

“…Temperature tests from -25ºC to +125ºC have shown no significant effect with respect to the results reported in Table I. According to previous characterization of individual electronic components in the CMOS process [8], the performance for temperatures down to -90ºC is expected to be correct as well.…”

“…Several test chips, with their corresponding experimental setups, irradiation campaigns, and low temperature measutherements, were employed for the characterization of total ionizing dose (TID) effects, singleevent effects (SEE), and low temperature behavior. A basic RHBD digital library was designed as part of this process [8].…”

A Front-End ASIC for a 3-D Magnetometer for Space Applications by Using Anisotropic Magnetoresistors

“…The total deviation is less than 0.8% and correlates with the variation of the bandgap. According to previous characterization of individual electronic components in the CMOS process [13], the performance for temperatures down to −90°C is expected to be correct as well.…”

“…The design of this ASIC for space applications builds on previous work oriented to the characterization of radiation and low temperature effects on the selected standard CMOS process [13]. Specific RHBD techniques have been employed in this ASIC.…”

CMOS Rad-Hard Front-End Electronics for Precise Sensors Measurements

“…Previous work to the design of this rad-hard ASIC was needed in order to characterize the selected standard 0.35 µm CMOS process against radiation and the extended temperature range, including several irradiation campaigns with their corresponding test chips and experimental setups [24]. As part of this process, a basic radiation-hardened digital library was also designed.…”
