In electronics, diode modelling refers to the mathematical models used to approximate the actual behaviour of real diodes to enable calculations and circuit analysis. A diode's I-V curve is nonlinear (it is well described by the Shockley diode law). This nonlinearity complicates calculations in circuits involving diodes so simpler models are often required.
AI-based automatic extraction and optimization method of diode model parameters
The application discloses an AI-based diode model parameter automatic extraction and optimization method, and belongs to the technical field of electronic design.The application solves the problem that the existing diode model parameter extraction method is seriously dependent on manual experience, the process is complicated and time-consuming, and it is difficult to stably obtain high-precision and strong generalization capability model parameters from nonlinear data under the influence of temperature and process deviation.The application constructs an intelligent mapping model from macro electrical characteristics to microscopic model parameters by adaptively denoising and multidimensional feature engineering on measured data, and finally generates a high-fidelity diode electronic design model by combining global optimization of physical constraints, so as to realize high-precision, high-efficiency and full-automatic extraction and optimization of key model parameters such as diode saturation current, ideal factor and series resistance, thereby improving the efficiency, automation level and cross-condition robustness of model extraction.
