Compact Model Validation Strategies Based on Dedicated and Benchmark Circuit Blocks for the mm-Wave Frequency Range

Abstract

This paper presents a methodology for compact model evaluation and validation at circuit level for RF and mm-wave applications. Accurate compact models are a prerequisite for efficient circuit design but currently modeling engineers lack of suitable verification procedures. In this work we detail a methodology to fulfill these requirements together with circuit examples, starting from the simplest differential pair to the most advanced four stage differential LNA working at 220GHz. It is shown that a complete hierarchy of validation circuits (from the simplest circuit to the most complex) provides a new perspective with respect to the crucial task of model qualification but also directions for future compact model developments.
