Voltage-dependent die RC modeling for system-level power distribution networks

摘要

Techniques for determining the voltage-dependent capacitance of a circuit are described herein. In one embodiment, a method for determining voltage-dependent capacitance of a circuit comprises measuring a parameter of the circuit at each one of a plurality of voltages, and, for each voltage, determining a capacitance of the circuit at the voltage by fitting a resistor-capacitor (RC) model of the circuit to the measured parameter of the circuit at the voltage.
