Device-circuit models for extreme environment space electronics

To design wide-temperature radiation-tolerant electronic systems for space missions and predict their characteristics and reliability in space, advanced models and simulation tools are required at multiple levels. Detailed, physics-based three-dimensional (3D) technology computer-aided-design (TCAD) device models, coupled in mixed-mode with external circuit models, enable accurate simulation and prediction of space electronics performance in extreme environments. We show the importance of correct device physics models for accurate computation of both steady-state and transient characteristics. Mixed-mode coupling of a realistic load circuit with the 3D TCAD device model is critical to be able to compute single-event transient waveforms and circuit characteristics that reflect well experimental results.
