By Kelvin Yuk, G. R. Branner and David McQuate First appears: IEEE MTT-S Int. Microw. Symp., pp. 753-756, Jun. 2009. A new empirical large-signal model for high-power GaN HEMTs utilizing an improved drain current (Ids) model is presented. The new
A new, simplified empirical large-signal model for high power microwave SiC MESFETs is presented. A generalized drain current source equation is developed, allowing close predictions of both pulsed and static IV characteristics, which vary significan
Investigation of power generation microdevices that utilize micromachining or MEMS for use in portable and self-powered systems. Autonomous and portable devices demand the need for small, lightweight energy supplies that can replace the use of conven
Using micro-scale fabrication and high voltage technologies, a fluid analysis system based on the transportation of fluid droplets by dielectrophoresis (DEP) can be developed. This thesis describes the development of a two-dimensional high voltage
Nowadays, there is a million of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) in digital, analog, and mixed-signals circuits, and noise in transistors has limited the minimum signal level that a circuit can process with acceptable quali
