Kurzfassung englisch:
IC input characteristics are important parameters for proximity coupling (13.56 MHz) transponders. Modeled as voltage-dependent capacitor (Cic ) and resistor (Ric ) connected in parallel, they are typically measured using an LCR meter. In this work, we introduce a nonlinear, custom-define circuit component (IC-component) based on LCR meter measurement results that is used within our simulation framework for predicting contactless performance metrics (e.g., minimum operating magnetic fiel strength Hmin ). Combined with linear S-parameter models from EM simulations of transponder antennas on a standardized test setup (ISO test PCD assembly), the IC-component is used in nonlinear circuit simulations to predict Hmin . Due to LCR meter´s input limitations, it is difficult to cover the entire range for predicting certain performance metrics at higher H-levels (e.g., IC robustness). Therefore, we also present a method that utilizes the ISO test PCD assembly and determines IC input characteristics of a transponder DUT. This method (Cic and Ric extraction method) measures the assembly´s output voltages up to higher H-levels and uses them as input to the system´s linear model. IC input characteristics, obtained as a function of measured voltages, are thereby extended towards higher H-levels and can be added to the IC-component, so that additional contactless performance metrics can be predicted by our simulation framework.
