    • A 12-bit 150-MHz 1.25-mm2 CMOS DAC 

      He, Y.; Jiang, J.; Sun, Y. (Institute of Electrical and Electronics Engineers (IEEE), 2004)
      This paper presents a 12-bit 150-MHz current steering DAC with hierarchical symmetrical switching sequence that compensates gradient errors. The circuit of the DAC employs segmented architecture; the least significant bits ...

    • CMOS R-MOSFET-C fourth-order Bessel filter with accurate group delay 

      He, Y.; Jiang, J.; Sun, Y. (Institute of Electrical and Electronics Engineers (IEEE), 2002)
      A fully differential R-MOSFET-C fourth-order Bessel active lowpass filter employing passive resistors and current-steering MOS transistors as a variable resistor is proposed. The implementation relies on the tunability of ...

    • Dynamic bandwidth assignment MAC protocol for differentiated services over GPON 

      Jiang, J.; Handley, M.R.; Senior, J.M. (2006)
      A dynamic bandwidth assignment MAC protocol is proposed to facilitate the upstream channel resource sharing and to support differentiated services over GPON. A new procedure for bandwidth reporting and a novel balance ...

    • GPON dynamic MAC protocol to support differentiated services 

      Jiang, J.; Handley, M.R.; Senior, J.M. (Institution of Engineering and Technology (IET), 2006)
      The Gigabit-capable passive optical network (GPON) has become an attractive and promising solution for the broadband access network. In this paper a novel dynamic bandwidth assignment protocol is proposed to both facilitate ...

    • GPON MAC Protocol Simulation for Encapsulated Ethernet Traffic 

      Senior, J.M.; Jiang, J.; Handley, Michael (2005-07-05)

    • A New efficient dynamic MAC protocol for the delivery of multiple services over GPON 

      Jiang, J.; Senior, J.M. (2009)
      The Gigabit-capable passive optical network (GPON) has become an attractive and promising solution for the broadband access network. It is apparent that an efficient medium access control (MAC) protocol is crucial not only ...

    • A truncated inner disc in the Seyfert 1 galaxy WKK 4438 

      Gallo, L. C.; Buhariwalla, M. Z.; Jiang, J.; D'Ammando, F.; Walton, D. J. (2022-09-05)
      Understanding if and when the accretion disc extends down to the innermost stable circular orbit (ISCO) is important since it is the fundamental assumption behind measuring black hole spin. Here, we examine the 2013 and ...
