This paper focuses on the modeling and analysis of different power distribution network (PDN) structures in 3D TSV ICs, including 3D full wave model and equivalent circuit model. In addition, a simplified equivalent circuit model of stacked PDN is proposed to analysis aspects influencing stacked PDN impedance, such as number of ground TSVs, number of TSV pairs and number of stacked layers. Analyses...
This paper proposed an equivalent source modeling method of the external complex electromagnetic interference (EMI) coupling on a cable connected to the electronic devices shielded by a chassis. The Norton theorem is used to develop the equivalent circuit of the EMI source. The moment method (MOM) in FEKO is used to calculate the short current and port impedance in Norton equivalent circuit, and curve...
This paper deals with the susceptibility prediction of integrated circuits against the conducted interference coupled on their power supply pins. An integrated operational amplifier OPA694 is studied as a first case. The integrated circuit electromagnetic (ICEM) model is used to describe the inner power distribution network of OPA694 by theoretical study and experimental measurement. A curve fitting...
This paper presents the analysis method of a capacitor-run signal-phase induction motor behavior by using circuit-coupled two-dimensional finite element method. In order to analyze the machines accuracy under rotating magnetic fields, the voltage source, run-capacitor and slide boundary are considered. The voltage coupled model included slip boundary and calculation method is presented, and the simulation...
