Polyharmonic distortion modeling

A polyharmonic distortion model (PHD) perfectly mated to existing nonlinear simulation capabilities is discussed to identify with advanced nonlinear measurements and model device under test (DUT). PHD modeling is a black-box, frequency-domain modeling technique which doesn't use any knowledge concerning the internal circuitry of the DUT. The information needed to construct a PHD model is acquired through externally simulating the signal ports of a DUT and measuring the response signals. The approach is suitable for distributed (dispersive) high-frequency applications including both the measurement techniques and the modeling approach, while the considerations are true for conventional linear S-parameters, which can be considered as a black-box frequency-domain modeling technique. The advantages of PHD, include technology independence, and effective sharing.
