System in a package design of a RF front end system using application specific reduced order models

'Package aware' IC Design has not only become advantageous, but also essential towards optimum performance of high-end systems. This is specifically true in RF front-end systems where the circuit performance is highly sensitive to package parasitics. Here, an intuitive design methodology has been presented that can help in the package aware design of the RF front end system using reduced order models. The reduced order models, whose order is based on the application of the package pins, are generated using krylov's sub space technique. This technique allows for a fine balance between the need for accuracy and time efficiency, during design and layout of the RF front-end.
