  • A Wide Modulation Range and PVT-Tolerant Spread-Spectrum Modulation Clock Generator

    Creator:
    Sun, Hyuk
    Abstract:
    This dissertation presents a phase domain in-loop-bandwidth spread-spectrum clock generation technique. In this proposed technique, a charge-based discrete-time loop filter is proposed to enable the phase domain in-loop-bandwidth spread-spectrum modulation without a delta-sigma modulator or time-to-digital converter. The in-loop-bandwidth modulation technique maximizes the loop bandwidth to improve phase noise suppression...

  • Proposed implementation of a near-far resistant multiuser detector without matrix inversion using Delta-Sigma modulation

    Creator:
    Myers, Timothy F.
    Abstract:
    A new algorithm is proposed which provides a sub-optimum near-far resistant pattern for correlation with a known signal in a spread-spectrum multiple access environment with additive white gaussian noise (AWGN). Only the patterns and respective delays of the K-1 interfering users are required. The technique does not require the inversion...
