1. Experimentally Based HFET Modeling for Microwave and Millimeter Wave Applications
Abstract : Transistor models are very important in the design of Monolithic Microwave Integrated Circuits (MMICs). Circuit simulations based on accurate transistor models are one of the keys to high circuit yield. Transistor models can also be used to trace problems in the device fabrication processes. READ MORE

3. Large-Signal Modeling of Microwave Transistors
Abstract : The development of computer aided design tools for microwave circuit design has increased the interest for accurate transistor models. The circuit complexity has grown as the CAD tools have been improved and the need to predict how non-linear circuits behave has also been increased. READ MORE

4. Characterization and Analysis of Surface Passivations and Gate Insulators for AlGaN/GaN Microwave HFETs
Abstract : The large bandgap of gallium nitride (GaN) and aluminum gallium nitride (AlGaN) offers an inherently high intrinsic breakdown field. When the materials are joined into the AlGaN/GaN heterostructure a 2-dimensional electron gas (2DEG) with a high electron density as well as high electron mobility is generated. READ MORE
