Abstract
A method for flattening an impedance of a power delivery network includes capturing a set of impedance parameters, obtaining an impedance of the power delivery network according to the set of impedance parameters, defining a target impedance, performing an importance calculation to determine a port, obtaining an intersection frequency according to the target impedance and the impedance of the power delivery network, selecting a decoupling capacitor according to the intersection frequency, and disposing the decoupling capacitor at the port. The method can reduce the impedance of the power delivery network to the target impedance and flatten the impedance to avoid the rogue wave phenomenon.
