  • Two-integrator detector for known-signal-in-noise identification

    Creator:
    Albright, Robert James
    Abstract:
    This thesis discusses the design and evaluation of an instrument that can detect known signals in noise. This detector uses two integrators to sense a difference in the received signal between half-cycles of the known signal. The detector is useful for sensing signals in the approximate frequency range of 100...

  • A comparison of substrate noise coupling in heavily doped and lightly doped substrates for mixed-signal circuits

    Creator:
    Ayers, James S.
    Abstract:
    An analysis of substrate noise coupling in mixed-signal circuits has been performed in the TSMC 0.25 [mu]m lightly doped and heavily doped CMOS processes. Methods to minimize noise coupling in both the chip design and board design phases are presented along with techniques for accurate circuit simulation of noise coupling....

  • A substrate noise coupling model for lightly doped CMOS processes

    Creator:
    Sadate, Aline C.
    Abstract:
    This thesis presents a design-oriented model for lightly doped CMOS substrates. The model predicts the substrate noise coupling between noisy digital and sensitive analog blocks in the early stages of the design. The model scales with the size and separation of these blocks and it is validated with device simulations...

  • Computationally efficient substrate noise coupling estimation in lightly doped silicon substrates

    Creator:
    Srinivasan, Kavitha
    Abstract:
    A Z-parameter based macromodel for characterizing the substrate noise coupling in a lightly doped substrate at low frequencies has been developed. The model is scalable with contact geometries and separation. The cross-coupling impedance between two contacts is modeled using an improved geometric mean distance formulation. This approach obviates the need...

  • Noise optimization for low-voltage CMOS audio preamplifier systems

    Creator:
    Brown, Matthew Eugene
    Abstract:
    There is a large and growing market for portable consumer audio products with very small size. As the size of these products is reduced, the area occupied by batteries becomes significant and hence limits the number of batteries to one. In order to build such small products, high levels of...

  • Resonant forward-biased guard rings for suppression of substrate noise in mixed-mode CMOS circuits

    Creator:
    Ficq, Bernard L.
    Abstract:
    Previous work at Stanford University has demonstrated that inductance in the substrate connection is the principal problem underlying the coupling of digital switching noise into analog circuits. The low impedance substrate can be treated as a single node over a local area. Switching in the digital circuits produces current transients...

  • Analysis and modeling of substrate noise coupling for NMOS transistors in heavily doped substrates

    Creator:
    Hsu, Shu-ching
    Abstract:
    This thesis examines substrate noise coupling for NMOS transistors in heavily doped substrates. The study begins with the analysis of an NMOS transistor switching noise in a digital inverter at the device level. A resistive substrate network for the NMOS transistor is proposed and verified. Coupling between N+- P+ contacts...

  • A test fixture and deembedding procedure for high-frequency substrate characterization

    Creator:
    Webb, Kyle M.
    Abstract:
    At frequencies exceeding 1-2 GHz, the substrate network models used in substrate coupling simulation must account for the reactive nature of the substrate. Unlike at low frequencies, where the purely resistive substrate models can be validated through DC resistance measurements, these high-frequency models, comprising reactive components, must be validated through...

    Creator:
    Hill, Douglas Glenn
    Abstract:
    Periodic signals hidden in noise may be detected by using correlation techniques This thesis presents a study of how correlation is approximated statistically, and carried out electronically. The ability to detect periodic signals in noise, using correlation, is justified mathematically in the first portion of the thesis. The discussion is...

    Abstract:
    A new method is presented to compress switching information in large digital circuits. This is combined with an efficient approach of generating the noise signatures of cells in a digital library that results in an accurate and efficient approach for estimating the noise generated in digital circuits. This method provides...
