This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract This thesis describes the design and implementation of a fully monolithic 10 Gb/s phase and frequency-locked loop based clock and data recovery (PFLL-CDR) integrated circuit, as well as the Verilog-A modeling of an asynchronous serial link based chip to chip communication system incorporating the proposed concept. The proposed design was implemented and fabricated using the 130 nm CMOS technology offered by UMC (United Microelectronics Corporation). Different PLL-based CDR circuits topologies were investigated in terms of architecture and speed. Based on the investigation, we proposed a new concept of quarter-rate (i.e. the clocking speed in the circuit is 2.5 GHz for 10 Gb/s data rate) and dual-loop topology which consists of phase-locked and frequency-locked loop. The frequency-locked loop (FLL) operates independently from the phase-locked loop (PLL), and has a highly-desired feature that once the proper frequency has been acquired, the FLL is automatically disabled and the PLL will take over to adjust the clock edges approximately in the middle of the incoming data bits for proper sampling. Another important feature of the proposed quarter-rate concept is the inherent 1-to-4 demultiplexing of the input serial data stream. A new quarter-rate phase detector based on the non-linear early-late phase detector concept has been used to achieve the multi-Giga bit/s speed and to eliminate the need of the front-end data pre-processing (edge detecting) units usually associated with the conventional CDR circuits. An eight-stage differential ring oscillator running at 2.5 GHz frequency center was used for the voltage-controlled oscillator (VCO) to generate low-jitter multi-phase clock signals. The transistor level simulation results demonstrated excellent performances in term of locking speed and power consumption. In order to verify the accuracy of the proposed quarter-rate concept, a clockless asynchronous serial link incorporating the proposed concept and communicating two chips at 10 Gb/s has been modelled at gate level using the Verilog-A language and time-domain simulated.

Download or read book A 26 28 gbps Clock and Data Recovery System with Embedded Equalization in 65 nm CMOS for 100GbE written by Li Sun and published by . This book was released on 2013 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: A power and area efficient approach to embed a continuous time linear equalizer (CTLE) into a clock and data recovery (CDR) circuit for the next generation 100GbE system is presented in this work. The proposed merged CDR/equalizer system is implemented in 65-nm CMOS without extra power penalty, and achieves full-rate operation up to 28-Gb/s. Current-mode-logic (CML) with shunt peaking loads and customized differential pair layout are used to extend the circuit bandwidth. To minimize the area penalty, customized stacked differential inductors have been designed. These inductors achieve an inductance density 3.2 times higher than the standard single-layer design from the PDK library. The CDR/equalizer core occupies 0.33 mm2 and draws 104 mA from a 1-V supply. The measured BER of the recovered data is less than 10-12 at 27-Gb/s for 211-1 400mVpp input PRBS data. The measured recovered clock and data rms jitter is 1.0 and 2.6 ps, respectively. The CDR is able to lock to inputs from 26-28-Gb/s with 29-1 PRBS pattern. The embedded equalizer enables the CDR to recover a 26-Gb/s 27-1 PRBS data with BER
Download or read book Performance Analysis for Clock and Data Recovery Circuits Under Process Variation written by and published by . This book was released on 2007 with total page 100 pages. 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.

Download or read book Design and Modeling of a Clock Data Recovery CDR Circuit written by Zainab binti Mohamad Ashari and published by . This book was released on 2013 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clock data recovery (CDR) circuits are in high demand due to development in communication technology such as improvements in transmit/receive processing and GHz transfer bandwidths via wired and wireless media. Large bandwidth data with high transfer rates encounter several major problems at the reception. Electrical signals are easily distorted with large bandwidth data when transmitted at high speeds. Existence of noise will cause disturbance or undesired signals at the output of the system. Minimizing the effects of jitter in CDR system is important to protect the signal from disturbance and to maintain low phase noise. A 5 Gbps clock data recovery circuit using PLL approach is proposed in this work. Hardware Description language, Verilog-AMS has been implemented as a modeling language for CDR using SMASH Dolphin Integrated software. The architecture of the proposed PLL CDR circuits incorporates a phase detector, RLC low-pass filter, voltage-controlled oscillator, and divider. Evaluation of the CDR performance is based on the design, frequency, transfer rate, supply voltage, and phase noise. The proposed circuit has a simple configuration powered using low supply of 1.0 V and operates in high speed of 5 Gbps. The phase noise performance is measure using four different offsets. Less phase noise of -130.29 dBc/Hz is generated without jitter added on it. To simulate jitter from 1 MHz to 100 GHz a pulse is added in each block of the CDR circuit and the circuit's performance is evaluated. CDR with jitter from 10 GHz up to 100 GHz at VCO produces the highest phase noise at the output port of -125.10 dBc/Hz. The PLL-based CDR circuit is affected when jitter pulses is added at the VCO. The proposed PLL-based CDR circuit is suitable for PCIe application with 5 Gbps transfer rate, low supply voltage, and has low phase noise.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in technology and the introduction of high speed processors have increased the demand for fast, compact and commercial methods for transferring large amounts of data. The next generation of the communication access network will use optical fiber as a media for data transmission to the subscriber. In optical data or chip-to-chip data communication, the continuous received data needs to be converted to discrete data. For the conversion, a synchronous clock and data are required. A clock and data recovery (CDR) circuit recovers the phase information from the data and generates the in-phase clock and data. In this dissertation, two clock and data recovery circuits for Giga-bits per second (Gbps) serial data communication are designed and fabricated in 180nm and 90nm CMOS technology. The primary objective was to reduce the circuit power dissipation for multi-channel data communication applications. The power saving is achieved using low swing voltage signaling scheme. Furthermore, a novel low input swing Alexander phase detector is introduced. The proposed phase detector reduces the power consumption at the transmitter and receiver blocks. The circuit demonstrates a low power dissipation of 340[mu]W/Gbps in 90nm CMOS technology. The CDR is able to recover the input signal swing of 35mVp. The peak-to-peak jitter is 21ps and RMS jitter is 2.5ps. Total core area excluding pads is approximately 0.01mm2.
