DC Cryogenic Modeling of Open-Source SkyWater 130 nm MOSFETs at 77 K Using BSIM4
The study systematically characterized and modeled SkyWater 130nm MOSFETs at 77 K, a temperature relevant for liquid argon detectors in high-energy physics. Researchers developed an isothermal BSIM4 model, achieving an average relative RMS error of about 20% compared to measurements. This work provides open-source, SPICE-compatible models for cryogenic circuit design.
