Abstract: The primary focus of this paper is to discuss the modeling of jitter caused by power supply noise (PSN), named power supply induced jitter (PSIJ). A holistic discussion is presented from the basics of power delivery networks to PSN and eventually to the modeling of PSIJ. The in-depth details and a review of several methodologies available in the literature for the estimation of PSIJ are presented.

Abstract: Estimation of jitter in early design cycle of an SoC is necessary to avoid jitter budget conflicts in the design. In this paper, an analysis of power supply induced jitter in a commonly used voltage mode driver architecture in serial links is discussed. The circuit used for the analysis is designed in 28nm FD-SOI technology but the analysis is technology independent. Jitter induced by noise in power delivery networks is analyzed by a transfer function from power supply to the output by a small signal equivalent model. The analysis can be extended generically for System-On-Chip (SoC) level design considerations.

Abstract: With the advancement of VLSI technology, the effect of jitter is becoming more critical on high speed signals. To negate the effect of jitter on these signals, the causes of jitter in a circuit need to be identified by decomposing the jitter. In this paper, a comparative analysis of various jitter estimation techniques is presented. The statistical domain methods are based on fitting techniques while the frequency domain methods are based on frequency spectrum analysis. This work describes both statistical domain methods and frequency domain methods. Further, their strengths and limitations are discussed. The algorithms are implemented in MATLAB and the results are extensively verified with Agilent ADS.

Abstract: This paper presents the timing error and power supply induced jitter (PSIJ) analyses of an inverter based high-speed comparator, including the design of common-mode body biasing feedback circuitry. Both the main circuit and the supporting circuitry have been designed and implemented in a standard 28 nm CMOS technology with power supply of 0.9 V. The closed-form transfer function of the comparator including biasing circuitry, used in PSIJ analysis, is derived using symbolic admittance method. The mathematical model shows an agreement with the simulation and exhibits 7.4% of mean percentage error (MPE).

Abstract: An analysis of power supply induced jitter in a high speed serial link is presented in this paper. An equivalent reduced model for serial link is used for the analysis. Jitter induced by the ripples in power delivery network is analyzed by a small signal equivalent model. The effect is modeled by a transfer function which is not technology specific and can be used generically for System-On-Chip (SoC) level design considerations. The analysis is supported by experimental results by simulation in 130nm BiCMoS RF technology and 28nm FDSOI technology (both technologies are of STMicroelectronics).

Abstract: THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

Abstract: An efficient methodology for estimation of power supply induced jitter (PSIJ) in high-speed designs is presented. Semianalytical expressions for jitter are derived based on separating the large signal response and the small signal noise response and subsequently combining the results. Proposed simplified relations enable the designers to estimate the PSIJ based on a single bit simulation. Proposed methods are validated on several examples of voltage-mode driver circuits, designed in different technologies and in the presence of different types of noise sources.
