Microwave Behavioral Modeling - Towards a Universal Device Model Format [From the Guest Editor´s Desk]

The three articles in this special section focus on the physics-based semiconductor devices based on so-called behavioral models. models belonging to the second group. with the advent of circuit simulators, device models became a need for computer aided integrated circuit design platforms. Today, they are common tools in the daily work of all circuit designers. Models are mathematical representations of the device operation, which are used in both circuit simulators and manual analysis tools. They can be classified as describing the internal device physics???the physics-based models???or only the device???s observable input and output port behavior, or behavioral modeling.
