  • Computer analysis of a class of acoustic signals

    Creator:
    Miller, Michael Robert
    Abstract:
    A procedure for displaying cursory computer analyses of time series acoustic signals is described. The graphic presentation is optimized for visual analysis. The results displayed represent time series signals and/or Power Spectral Density estimates. Both hardware and software components of the procedure are described and compared with current methods. Suggestions...

  • Random dopants and low-frequency noise reduction in deep-submicron MOSFET technology

    Creator:
    Miller, Drake A.
    Abstract:
    The future of mixed-signal, memory, and microprocessor technologies are dependent on ever increasing analog and digital integration, higher cell densities, and demand for more processing power. As a result MOSFET device dimensions continue to shrink to meet these demands. A side effect of device scaling is increased variability at each...

  • A DC-DC converter architecture for low-power, high-resistance thermoelectric generators for use in body-powered designs

    Creator:
    Miller, Brian A.
    Abstract:
    This thesis presents a low power DC-DC converter suitable for harvesting energy from high impedance thermoelectric generators (TEGs) for the use in body powered electronics. The chip has been fabricated in a 130nm CMOS technology. To meet the power demands of body powered networks, a novel dual-path architecture capable of...

  • Design considerations for fast-settling operational amplifiers

    Creator:
    Yang, Howard C.
    Abstract:
    The design considerations for fast-settling operational amplifiers (opamps) differ significantly between sampled-data switchedcapacitor (SC) and conventional continuous-time applications. In SC circuits, the shape of the output voltage waveform of an opamp is of no consequence provided that the output settles to within a specified tolerance of its steady-state value prior...

  • Low-voltage Tracking RC Compensated OTA and a Rail-to-Rail Input and Output Operational Amplifier

    Creator:
    Kuo, Yu-Wen
    Abstract:
    The operational transconductance amplifier (OTA) is a fundamental building block in analog and mixed-signal systems. This research describes a process-, voltage-, and temperature- (PVT) insensitive low-voltage tracking RC compensation scheme considered for two-stage CMOS OTAs, which cancels the pole due to the load capacitance using a Miller zero generated by...

  • Energy-efficient OTA architectures using load-pole cancellation

    Creator:
    Ramakrishna, Pavan Kumar
    Abstract:
    The CMOS two-stage Operational Transconductance Amplifier (OTA) has been a key enabler for mixed-signal IC design for nearly four decades . This research focuses on a modified two-stage CMOS OTA that features load-pole cancellation (LPC); i.e., the resulting architecture is essentially a two-stage CMOS OTA with no load capacitance. The...

  • gm/ID Design Techniques for Low-power High-performance CMOS Analog Integrated Circuits

    Creator:
    Aueamnuay, Chaiyanut
    Abstract:
    The gm/ID-based design of analog integrated circuits introduced in 1996 employs an empirical transistor sizing methodology using SPICE-generated lookup tables that enables good agreement between simulations and specifications. This thesis introduces a new SPICE lookup table that extends the gm/ID approach to the Miller pole-splitting frequency compensation of the classical...

  • Design techniques for wideband low-power Delta-Sigma analog-to-digital converters

    Creator:
    Wang, Yan
    Abstract:
    Delta-Sigma (ΔΣ) analog-to-digital converters (ADCs) are traditionally used in high quality audio systems, instrumentation and measurement (I&M) and biomedical devices. With the continued downscaling of CMOS technology, they are becoming popular in wideband applications such as wireless and wired communication systems,high-definition television and radar systems. There are two general realizations...

  • A Fully Integrated Bio-potential Low-noise Amplifier Utilizing Capacitor Multipliers

    Creator:
    Yong, OnnLim
    Abstract:
    In any biomedical signal acquisition system, a front-end amplifier is needed to amplify low amplitude bio-signals while filtering out any unwanted low-frequency artifacts. The design of low frequency poles within the sub-Hz range implies very large time-constants which goes against system integrability. In recent years, the pseudo resistor has been...
