| Abstract | An analog-to-digital converter (ADC) is an essential device in mixed mode systems. The performance of the ADC, however, is deteriorated by coupled power supply noises through hierarchical chip-PCB power distributed networks (PDNs). In order to design a high-performance system, modeling and analysis of power supply noise effects on the ADC are necessary, as the power supply noise is coupled to the circuit through the hierarchical PDN structure in multilayer PCB substrates. In this paper, a hybrid model is proposed for analysis of power supply noise effects on the ADC. The model combines two modeling mechanisms. First, the coupling ratio of the power supply noise is derived by the combined model of hierarchical PDNs at the PCB and the chip. Second, an analytical model is proposed using equivalent circuits for analysis of the power supply noise effects on the ADC. The ADC is designed using a 0.13um CMOS process. The proposed model and analysis are verified based on a simulation from 100kHz to 4GHz. The performance of the ADC is dominantly affected by characteristics of the on-chip circuit under 100MHz. It is also confirmed that the Effective Number of Bits (ENOB) of the ADC is strongly dependent on the hierarchical PDN impedance over 100MHz. Furthermore, there are peak points caused by inter-modulation (IMD) and cavity resonances of PDN structures. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
