Resonance Analysis Methods for Estimation of FTB Propagation in Integrated Circuits

Fast Transient Burst (FTB) tests are performed on Integrated Circuits (IC) in order to simulate a common mode conducted disturbance on supply. Power network distribution is known as the main contributor of FTB weakness of the IC. Due to electromagnetic disturbance, it is not possible to perform measurements during the FTB test. This paper focuses on resonance analysis of the Power Distribution Network (PDN), based on dedicated measurement set-ups. Indeed, the resonance frequencies of the PDN are correlated with the propagation of the FTB signal injected in the circuit. Finally, this study is going to allow us to increase the robustness of the circuit.
