Available in PDF, EPUB and Kindle. Book excerpt: Baud rate clock and data recovery circuits are critical to high speed serial links since these require only one sample per data period thereby requiring low speed samplers and comparators. This work models and discusses the backend of one particular Baud rate CDR – Mueller Muller, and analyses some of the building blocks of the CDR – Phase Detector, Phase Interpolator and the Quadrature Phase Generator. Firstly, a PAM-4 Quadrature Phase Detector operating at 80Gb/s is discussed. The challenges associated with designing a Mueller-Muller PD for an asymmetric channel are discussed and one way to resolve this issue is proposed. Then the underlying digital blocks that make up the Phase detector are expanded upon. Secondly, a 64-step digitally controlled Phase Interpolator running at 16GHz clock rate is analyzed and its design challenges with regards to achieving linearity and ensuring duty cycle fidelity are explored. Finally, a Quadrature Phase Generator with digital delay control is analyzed. It is modeled at 16GHz clock rate and the range/resolution problem and its impact on clock jitter is explored.

Available in PDF, EPUB and Kindle. Book excerpt: New System-Level Techniques for Optimizing Signal/Power Integrity in High-Speed Interfaces--from Pioneering Innovators at Rambus, Stanford, Berkeley, and MIT As data communication rates accelerate well into the multi-gigahertz range, ensuring signal integrity both on- and off-chip has become crucial. Signal integrity can no longer be addressed solely through improvements in package or board-level design: Diverse engineering teams must work together closely from the earliest design stages to identify the best system-level solutions. In High-Speed Signaling, several of the field’s most respected practitioners and researchers introduce cutting-edge modeling, simulation, and optimization techniques for meeting this challenge. Edited by pioneering experts Drs. Dan Oh and Chuck Yuan, these contributors explain why noise and jitter are no longer separable, demonstrate how to model their increasingly complex interactions, and thoroughly introduce a new simulation methodology for predicting link-level performance with unprecedented accuracy. The authors address signal integrity from architecture through high-volume production, thoroughly discussing design, implementation, and verification. Coverage includes New advances in passive-channel modeling, power-supply noise and jitter modeling, and system margin prediction Methodologies for balancing system voltage and timing budgets to improve system robustness in high-volume manufacturing Practical, stable formulae for converting key network parameters Improved solutions for difficult problems in the broadband modeling of interconnects Equalization techniques for optimizing channel performance Important new insights into the relationships between jitter and clocking topologies New on-chip measurement techniques for in-situ link performance testing Trends and future directions in signal integrity engineering High-Speed Signaling thoroughly introduces new techniques pioneered at Rambus and other leading high-tech companies and universities: approaches that have never before been presented with this much practical detail. It will be invaluable to everyone concerned with signal integrity, including signal and power integrity engineers, high-speed I/O circuit designers, and system-level board design engineers.

Book excerpt: This thesis presents an adaptive baud-rate CDR with CTLE and 1-tap DFE. The novelty in this design is the adaptation engine tailored for baud-rate clock and data recovery where the comparators for the DFE and the PD are shared to save power. A testchip was fabricated in TSMC 28nm CMOS. The adaptation engine is demonstrated for 34-36Gb/s operation with a Tyco 5" channel resulting in 15.05-18.25dB channel losses. At 35Gb/s, the total power consumption is measured to be 106.3mW or a FOM of 3.04pJ/bit. This thesis also presents a 2x half-baud-rate clock and data recovery technique with 2x oversampling at half-baud-rate (every other UI). A testchip was also fabricated in TSMC 28nm CMOS. A 30Gb/s 2x half-baud-rate CDR was tested with a Tyco 5" channel with 13.06dB of loss. The total power consumption is measured to be 79.2mW or a FOM of 2.64pJ/bit.

Book excerpt: Baud-rate clock recovery (CR) is gradually gaining popularity in modern serial data transmission systems since these CR techniques do not require edge-samples for extracting timing information. However, previous baud-rate techniques for high-speed serial links either rely on specific 4-bit patterns or uncorrelated random data. This work describes the modeling and design of analog filter front-end aided baud-rate CR schemes. Unlike other baud-rate schemes, this technique is not constrained by the properties of the input random data.Firstly, the thesis develops a hardware-efficient baud-rate algorithm that requires only the slope information of the incoming random data. Called modified sign-sign minimum mean squared error (SSMMSE), this algorithm adjusts the clock sampling phase until the slope is zero through a bang-bang control loop. Secondly, the performance of a modified SSMMSE phase detector is investigated and compared with a conventional edge-sampled phase detector. It is shown that, at severe noise levels, the proposed modified SSMMSE method has better performance compared to the edge-sampled method for equal loop bandwidths. Thirdly, the thesis investigates different hardware-efficient slope detection techniques. Both passive and active filter based slope detection techniques are demonstrated in this work. In addition to slope generation, the active filter performs linear equalization as well. However, the passive filter generates the slope information at higher speeds than the active filter and also consumes less power. The two filters are used to recover a 2-GHz clock by using an external bang-bang loop. In short, the thesis demonstrates that area and power savings can be achieved by utilizing slope information from front-end filters without compromising the performance of the CR unit.

Available in PDF, EPUB and Kindle. Book excerpt: Clock and data recovery circuits play a very important role in modern data communication systems. It has very wide application in many areas, such as optical communications and interconnection between chips [1]. Today in IC industry, the shrinkage of feature size increasingly enlarges the uncertainty of circuit performance caused by process variation. As the data transmission speed dramatically increases, this uncertainty will heavily affect the clock and data recovery circuit performance and reliability in communication systems. Thus, research on performance variation of a clock and data recovery circuit caused by process variation is meaningful. The conclusion will have significant influence on chip testing. In this research, a clock and data recovery circuit is laid out by TSMC 180nm technology. The performance variation caused by process variation is investigated by HSPICE simulation, and compared with the theoretical analysis results derived through the mathematical model of the clock and data recovery circuit. The results demonstrate that our theoretical model matches well with the real simulations. Both theoretical and simulation results also indicate that process variations in the low pass filter have significant impact on performance parameters such as damping ratio, natural frequency, and lock time of the clock and data recovery circuit.
