The paper presents the coupling of edge finite elements with a circuit by means of surface impedance boundary conditions for wave problems in the frequency domain. The coupling is based on surface impedance boundary conditions. The derivation of the method is described. A couple of numerical problems demonstrate the validity.
The lumped models of several capacitors in SMD-0603 package are extracted from S-parameter measurements. The S-parameters of the SMD components are obtained: (i) by modelling the RF connector and transmission lines and de-embedding, and (ii) by directly calibrating the reference plane to the SMD component using on-board calibration standards. The extracted… (More)
An interchangeable black-box model of an integrated circuit block for time-domain simulations of the direct power injection (DPI) immunity test is presented. An artificial neural network implemented as a Verilog A module is used to build a model of a bandgap reference circuit sub-block. Being a part of a larger schematic of interconnected circuit blocks,… (More)
