RF technology optimization by a fast method for linearity determination

This paper introduces a new methodology to determine the small signal linearity of a device directly from 2-port Y-parameters. With that approach, a 10-fold reduction of the simulation time in a comparison with traditional transient or harmonic balance simulations can be achieved, which enables a fast route for RF device and process technology optimization in an industrial environment. It is also shown that the linearity performance should be taken into account for the device optimization.
