ABSTRACT:
Methods for analyzing circuit distortion based on contributions from separate circuit elements are presented. Local approximations that do not require high-order derivatives of device models are developed near an operating point for calculating distortion summaries including compression summaries and second-order intermodulation (IM2) distortion summaries.
