Download or read book Delay Flip flop DFF Metastability Impact on Clock and Data Recovery CDR and Phase locked Loop PLL Circuits written by Alfred Sargezisardrud and published by . This book was released on 2014 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling delay flip-flops for binary (e.g., Alexander) phase detectors requires paying close attention to three important timing parameters: setup time, hold time, and clock edge-to-output (or briefly C2Q time). These parameters have a critical role in determining the status of the system on the circuit level. This study provided a guideline for designing an optimum DFF for an Alexander phase detector in a clock and data recovery circuit. Furthermore, it indicated DFF timing requirements for a high-speed phase detector in a clock and data recovery circuit. The CDR was also modeled by Verilog-A, and the results were compared with Simulink model achievements. Eventually designed in 45 nm CMOS technology, for 10 Gbps random sequence, the recovered clock contained 0.136 UI and 0.15 UI peak-to-peak jitter on the falling and rising edges respectively, and the lock time was 125 ns. The overall power dissipation was 21 mW from a 1 V supply voltage. Future work includes layout design and manufacturing of the proposed design.

This book was released on 2014 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Delay Flip Flop (DFF) is used in the phase detector circuit of the clock and data recovery circuit. A DFF consists of the three important timing parameters: setup time, hold time, and clock-to-output delay. These timing parameters play a vital role in designing a system at the transistor level. This thesis paper explains the impact of metastablity on the clock and data recovery (CDR) system and the importance of calibrating the DFF using a metastable circuit to improve a system's lock time and peak-to-peak jitter performance. The DFF was modeled in MATLAB Simulink software and calibrated by adjusting timing parameters. The CDR system was simulated in Simulink for three different cases: 1) equal setup and hold times, 2) setup time greater than the hold time, and 3) hold time greater than the setup time. The Simulink results were then compared with the Cadence simulation results, and it was observed that the calibration of DFF using a metastable circuit improved the CDR system's lock time and jitter tolerance performance. The overall power dissipation of the designed CDR system was 2.4 mW from a 1 volt supply voltage.

Download or read book A Digital Multiplying Delay Locked Loop for High Frequency Clock Generation written by Tushar Uttarwar and published by . This book was released on 2011 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Moore's Law continues to give rise to ever shrinking channel lengths, circuits are becoming more digital and ever increasingly faster. Generating high frequency clocks in such scaled processes is becoming a tough challenge. Digital phase locked loops (DPLLs) are being explored as an alternative to conventional analog PLLs but suffer from issues such as low bandwidth and higher quantization noise. A digital multiplying delay locked loop (DMDLL) is proposed which aims at leveraging the benefit of high bandwidth of DLL while at the same time achieving the frequency multiplication property of PLL. It also offers the benefits of easier portability across process and occupies lesser area. The proposed DMDLL uses a simple flip-flop as 1-bit TDC (Time Digital Converter) for Phase Detector (PD). A digital accumulator acts as integrator for loop filter while a [delta-sigma] DAC in combination with a VCO acts like a DCO. A carefully designed select logic in conjunction with a MUX achieves frequency multiplication. The proposed digital MDLL is taped out in 130nm process and tested to obtain 1.4GHz output frequency with 1.6ps RMS jitter, 17ps peak-to-peak jitter and -50dbC/Hz reference spurs.

Download or read book CMOS Continuous Time Adaptive Equalizers for High Speed Serial Links written by Cecilia Gimeno Gasca and published by Springer. This book was released on 2014-09-22 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the design of adaptive equalization solutions integrated in standard CMOS technology for high-speed serial links. Since continuous-time equalizers offer various advantages as an alternative to discrete-time equalizers at multi-gigabit rates, this book provides a detailed description of continuous-time adaptive equalizers design - both at transistor and system levels-, their main characteristics and performances. The authors begin with a complete review and analysis of the state of the art of equalizers for wireline applications, describing why they are necessary, their types, and their main applications. Next, theoretical fundamentals of continuous-time adaptive equalizers are explored. Then, new structures are proposed to implement the different building blocks of the adaptive equalizer: line equalizer, loop-filters, power comparator, etc. The authors demonstrate the design of a complete low-power, low-voltage, high-speed, continuous-time adaptive equalizer. Finally, a cost-effective CMOS receiver which includes the proposed continuous-time adaptive equalizer is designed for 1.25 Gb/s optical communications through 50-m length, 1-mm diameter plastic optical fiber (POF).
