mm-Wave Device Modeling

Circuit designers are mostly used to assume device models as given, instantiate their desired devices in their schematic windows, set up the simulation and run! They might perform their simulations in a number of different process corners and this is as much as they should worry about the whole notion of device modeling. mm-wave circuit design, at least for now, is an exception and both active and passive devices need extensive modeling. In this section, first reasons for this importance are discussed, then the device modeling procedure up to 100 GHz is presented and modeling results for single-transistor devices are shown. This follows by a discussion about measurement and de-embedding at these frequencies. Finally modeling of cascode devices are is included as an example of a multi-transistor structure.
