论文摘要
紧凑的半导体设备模型对于有效设计和分析大型电路至关重要。但是,传统的紧凑型模型开发需要大量的手动努力,并且可以跨越多年。此外,将新物理学(例如,辐射效应)纳入现有的紧凑模型并不小,可能需要从头开始重新开发。机器学习(ML)技术有可能自动化并显着加快紧凑型模型的发展。此外,ML提供了一系列建模选项,可用于开发针对特定电路设计阶段的紧凑型模型的层次结构。在本文中,我们探讨了三个这样的选项:(1)基于表的插值,(2)广义移动最小二乘和(3)馈送前进的深神经网络,以为P-N结二极管开发紧凑的模型。我们通过(1)将它们的电压电流特性与实验室数据进行比较,以及(2)使用这些设备来构建桥梁整流器电路,使用Spice样电路模拟来预测电路的行为,然后将这些预测与同一电路实验室测量进行比较,从而对这些“数据驱动”的紧凑型模型的性能进行了评估。
Compact semiconductor device models are essential for efficiently designing and analyzing large circuits. However, traditional compact model development requires a large amount of manual effort and can span many years. Moreover, inclusion of new physics (eg, radiation effects) into an existing compact model is not trivial and may require redevelopment from scratch. Machine Learning (ML) techniques have the potential to automate and significantly speed up the development of compact models. In addition, ML provides a range of modeling options that can be used to develop hierarchies of compact models tailored to specific circuit design stages. In this paper, we explore three such options: (1) table-based interpolation, (2)Generalized Moving Least-Squares, and (3) feed-forward Deep Neural Networks, to develop compact models for a p-n junction diode. We evaluate the performance of these "data-driven" compact models by (1) comparing their voltage-current characteristics against laboratory data, and (2) building a bridge rectifier circuit using these devices, predicting the circuit's behavior using SPICE-like circuit simulations, and then comparing these predictions against laboratory measurements of the same circuit.
