TCAD-based Model Extraction Flow for GaN HEMT Devices
This webinar will present a model parameter extraction methodology for GaN HEMT devices. This will include a review of the current SPICE compact models for GaN HEMT devices, with a discussion of Verilog-A and simulator built-in models. The input data for the model extraction is generated using TCAD device simulations. Specific advantages of this approach will be discussed, such as the ability to generate data in the absence and presence of self-heating. A SPICE model extraction flow will be illustrated. Various details will be addressed: how to deal with symmetric vs. asymmetric devices, how to set the device structure-related model parameters and how to setup various optimization steps.
What attendees will learn:
- Current status of SPICE compact models for GaN devices
- Verilog-A versus simulator built-in models
- Generating data using TCAD device simulation
- Data conversion for parameter extraction
- Extraction of SPICE model parameters for GaN HEMT devices
- Prerequisites
- Description of the flow
- Setting up the optimization steps
- Running the flow and illustrating the results
