  • Mullane, Brendan; O'Brien, Vincent (Springer, 2012)
    Direct Digital Synthesis (DDS) systems generate fine frequency resolution signals over a broad spectrum that are used in a wide variety of applications such as multi-mode RF, communications, measurements and test. A ...
  • Scanlan, Tony; O'Hare, Daniel; Halton, Mark; O'Brien, Vincent; Mullane, Brendan; Thompson, Eric (Emerald Group Publishing Ltd,, 2017)
    Purpose The purpose of this paper is to present analysis of the feedback predictive encoder based ADC (Analog-to-Digital Converter). Design/methodology/approach The use of feedback predictive encoder based ADCs presents ...
  • O'Brien, Vincent (University of Limerick, 2017)
    This thesis presents the analysis and design of dynamic element matching (DEM) decoders targeted at both discrete and continuous time oversampling delta sigma data converters. Discrete time delta sigma data converters ...
  • Mooney, James; Halton, Mark; Iordanov, Petar; O'Brien, Vincent (IEEE Computer Society, 2015)
                               Multi-bit sigma-delta based digital pulse width modulators (DPWM) are used in the control of DC-DC converters in order to achieve high resolution and therefore high output voltage accuracy at ...
  • O'Brien, Vincent; Scanlan, Anthony G.; Mullane, Brendan (Springer, 2017)
    This paper presents a dynamic element matching (DEM) decoder incorporating both intersymbol interference (ISI) and mismatch error shaping. From the analysis of ISI error in multi-bit DACs, an algorithm is developed ...
