Table Of Units

A.1 Collection of Variables and Constants for Different Applications

We provide two tables, depending on the application. Fundamentally, we would like to use units that keep each element value close to 1 (unity). The purpose of this is to keep the element values in the matrices as close as possible. It is intuitively obvious that an element in a matrix of is ignorable small compared to 1. Using the appropriate normalized units is a good way to keep the elements in the same orders of magnitude. Here, we give Tables A.1 and A.2, one for low-frequency power electronics and one for microelectronics and high- frequency circuits.
