Chip-Package Co-modeling & Verification of Noise Coupling & Generation in CMOS DC/DC Buck Converter
DC/DC Converters are now an essential part in a system due to the various needs of supply voltage that is necessary for different circuits in the system. However, there are many papers which have dealt for efficiency or for a novel structure that would be customized to the specific design, but few dealt with the noise characteristics of DC/DC Converters which could critically affect to the output supply voltage the target circuit would need. In this paper we analyzed the effect of noise to a DC/DC Converter in a chip-package co-design. We figured out that the decoupling capacitors on the PCB board cannot shield all the noise that could affect to the DC/DC converter, and on-chip decoupling capacitor for a DC/DC Converter would be necessary.
