The substrate contributes significantly to these parasitic elements and its modelling is a challenge, especially under large-amplitude excitation conditions for which harmonic distortion appears. This work focuses on the substrate-induced signal distortion modelling and simulations of integrated circuits on silicon-based substrates. The simulation approach developed in this thesis is relevant to the design of RF and mm-Wave circuits. As of yet, no satisfactory and widely applicable large-signal modelling tool is available that can capture substrate-induced signal distortion effects. A potential design flow to be of practical use to the Radio-Frequency Integrated Circuits design community is proposed in this work.Harmonic distortionModellingSimulationICs characterizationMillimeter-waveRadiofrequencySilicon-on-insulatortext::thesis::master thesisthesis:37802
