About the Physical Relevance of Optimizer-Based Extracted Model Elements with Gunter Kompa

Commonly small-signal model parameter extraction of microwave devices with a higher degree of complexity relies on optimization. This is outlined in more detail in my book Parameter Extraction and Complex Nonlinear Transistor Models. There are numerous optimization methods proposed in the literature. Based on a physical device model with a defined number of model elements …

Set the Appropriate Measuring Range for Consistent Model Parameter Extraction with Gunter Kompa

Measuring the scattering parameters of a microwave transistor to develop an appropriate small-signal device model, the question may come up about the minimum frequency range needed to extract reliable  model parameter values. This issue has been studied intensively for microwave devices based on GaN technology and discussed in detail in my book Parameter Extraction and …

Getting Broad and Thorough Understanding in the Field of Device Modeling and Model Parameter Extraction with Gunter Kompa

My published book titled Parameter Extraction and Complex Nonlinear Transistor Models concerns with the following three key topics: Small-signal model parameter extraction Large-signal device modeling Large-signal measurement techniques In my first post, dated December 17, 2019, I explained the limitation of using the standard 15-element FET model for modern high power multifinger GaN devices.
