Coupling between inductances in GaAs MMIC design G. Avitabile, A. Cidronali, G. Manes, G. BifFi Gentili Department of Electronic Engineering, University of Florence, 1-50139 Firenze, Italy ABSTRACT This paper describes the influence of the coupling between planar spiral inductors on the performances of a monolithic microwave linear circuit behaviour. An equivalent lumped-element model, developed using a full-wave approach, is discussed. The with the foundry model is compared with the standard foundry model. A GaAs MMIC LNA operating in 2.45 Ghz ISM-band is used as a benchmark for validating the model. 1 INTRODUCTION Computer aided design (CAD) tools are extensively used for the analysis and optimisation of microwave circuits. CADs sometime suffer for poor component modeling, thus, leading to a lack of effectiveness in non-standard situations. The modeling of both active, as well as passive components is receiving a considerable attention in order to extend the ap
