Improved modeling of isolated EDMOS in advanced CMOS technologies

摘要

Based on systematic measurements in CMOS 40nm bulk technology, we propose a new model for isolated Extended-Drain MOS (EDMOS) transistor. Our custom Spice macro-model includes main specific effects in high-voltage devices. In particular, the model accounts for the various parasitic bipolar components (PBCs) that are fully characterized. This model can cover various architectures, from bulk-Si to FDSOI.
