  • A Mixed-Mode Delay-Locked Loop Architecture
  • 2003
  • Ingår i: Proceedings of the 21st International Conference on Computer Design (ICCD), San Jose, 13-15 October 2003. - 1063-6404. - 0769520251 ; , s. 261-263
  • Konferensbidrag (refereegranskat)abstract
    • We present a mixed-mode delay-locked loop (DLL) architecture intended for multiple-phase clock generation. In contrast to analog DLLs, the proposed architecture allows for clock-gating; moreover circuit simulations indicate that its performance (in terms of maximum frequency, frequency range, and low-speed power dissipation) is superior to that of a previously-reported, purely digital DLL.

  • ASIC Implementation of Time-Domain Digital Back Propagation for Coherent Receivers
  • 2018
  • Ingår i: IEEE Photonics Technology Letters. - 1041-1135 .- 1941-0174. ; 30:13, s. 1179-1182
  • Tidskriftsartikel (refereegranskat)abstract
    • Digital back propagation (DBP) is often proposed and implemented offline for the mitigation of nonlinear impairments in long-haul fiber communications. However, complexity in terms of chip area and power consumption in a realistic application-specific integrated circuit implementation is yet to be determined. Here, we implement time-domain DBP (TD-DBP) in a 28-nm fully-depleted silicon-on-insulator process technology, considering digital implementation aspects such as limited-resolution arithmetic and finite-length filters. We choose as example a coherent optical transmission system, viz. a single-channel, single-polarization, and 20-GBd 16-QAM system, for which the DBP is known to perform well. For the considered system, we find that the TD-DBP can enable a reach increase from 3400 to 5300 km, at a power dissipation of <20 W (or, conversely, an energy dissipation of <230 pJ/bit), at a pre-FEC BER of 10-2.

  • Dynamic Equalizer Power Dissipation Optimization
  • 2016
  • Ingår i: 2016 Optical Fiber Communications Conference and Exhibition. - 9781943580071
  • Konferensbidrag (refereegranskat)abstract
    • We investigate power dissipation/performance trade-off in a 28nm ASIC implementation of a parallel dynamic equalizer. Over 50% dissipation improvement is possible by sample pruning during filter updates, with only minor tracking-performance reduction.

  • Ingår i: Optics InfoBase Conference Papers. - 2162-2701. - 9781943580231 ; , s. Article no 7937325-
  • Konferensbidrag (refereegranskat)abstract
    • We propose a nonlinear mitigation algorithm designed from an ASIC perspective, and analyze implementation aspects. Given 9 signal and 11 coefficient bits, reach is increased by 105% compared to linear compensation in single-channel 16-QAM transmission.

  • FlexSoC: Combining Flexibility and Efficiency in SoC Designs
  • 2003
  • Ingår i: Proceedings of 21st Norchip Conference. ; Riga, Latvia, s. 52-55
  • Konferensbidrag (refereegranskat)abstract
    • The FlexSoC project aims at developing a designframework that makes it possible to combine the computational speed and energy-efficiency of specialized hardware accelerators with the flexibility of programmable processors. FlexSoC approaches this problem by defining auniform programming interface across the heterogeneousstructure of processing resources. This paper justifies ourapproach and also discusses the central research issueswe will focus on in the areas of VLSI design, computerarchitecture, and programming and verification.

  • Implementing Constructive Alignment in a CDIO-oriented Master’s Program in Integrated Electronic System Design
  • 2010
  • Ingår i: Proceedings of European Workshop on Microelectronics Education. ; , s. 135-140
  • Konferensbidrag (refereegranskat)abstract
    • This presentation reports on the design and implementation of a Master’s program in Integrated Electronic System Design at Chalmers University of Technology from the perspectives of CDIO and constructive alignment. CDIO is an innovative educational concept originating from Massachusetts Institute of Technology (MIT) in which engineering fundamentals are stressed in terms of a Conceive, Design, Implement, and Operate process. Constructive alignment is a concept for creating an integrated learning environment where the teaching and learning activities are aligned with the assessment tasks to ensure that the achieved learning outcomes will correspond to the intended learning outcomes. In a process based on these two concepts, we have built a Master´s program that not only offers the basic theoretical background but also gives the student an opportunity to become competent in the skills that industry needs. Program focus is on the engineering process, on the technology platforms, and on the design tools and methodologies needed by the engineer to be able to contribute to the development of complex electronic systems and products while working in an engineering team.

  • Power Consumption of a Minimal-DSP Coherent Link with a Polarization Multiplexed Pilot-Tone
  • 2016
  • Ingår i: 42nd European Conference and Exhibition on Optical Communications, September 18-22, 2016, Düsseldorf. - 9783800742745
  • Konferensbidrag (refereegranskat)abstract
    • We experimentally study the trade-off between performance and DSP power consumption. While minimal DSP allows transmission of 16QAM at 5 GBaud, the symbol rate can be increased if anextra equalizer is added, leading to energy savings in optical components.
