Artificial Neural Network Modeling for Improved On-Wafer OSLT Calibration Standards

Abstract

We apply artificial neural networks (ANNs) to improve the modeling of on-wafer open-short-load-thru (OSLT) standards used for calibrating vector network analyzers. The ANNs are trained with measurement data obtained from a benchmark multiline thru-reflect-line (TRL) calibration. We assess the accuracy of an OSLT calibration using these ANN-modeled standards, and find that it compares favorably (less than a 0.02 difference in magnitude) to the bench mark multiline TRL calibration over a 40 GHz bandwidth. We also quantify the training errors and training times as a function of bother the number of training points and the number of neurons in the hidden layer.
