  • 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...

  • Architectural Solutions for Analog Imperfections in ΔΣ Analog-to-Digital Based Systems

    Creator:
    Zali Asl, Samira
    Abstract:
    For today’s ubiquitous portable devices, innovative integrated circuits with high performance yet very low power are necessary. As these devices are used to communicate and sense real world signals in the environment, analog-to-digital converters (ADC) and systems are the key interface circuits needed to digitize the sensed information and they...

  • Power efficient analog-to-digital converters using both voltage and time domain information

    Creator:
    Oh, Taehwan
    Abstract:
    As advanced wired and wireless communication systems attempt to achieve higher performance, the demand for high resolution and wide signal bandwidth in their associated ADCs is strongly increased. Recently, time-domain quantization has drawn attention from its scalability in deep submicron CMOS processes. Furthermore, there are several interesting aspects of time-domain...

  • 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...

  • Energy-efficient clock generation for communication and computing systems using injection locking

    Creator:
    Ma, Chao
    Abstract:
    The design of high-performance, high-speed clock generation and distribution becomes challenging in terms of phase noise, jitter and power consumption, due to the fast development of communication and computing systems. Injection locking is a promising clocking technique since it can significantly improve the energy efficiency, suppress the phase noise of...

  • High-performance Ring Amplifier based Analog-to-Digital Converters

    Creator:
    Hu, Hang
    Abstract:
    Ring Amplifier serves as a great candidate both for precision amplification and fast integration in the discrete time system. It can be utilized in high-performance analog-to-digital converters (ADCs). In high-speed ADC utilizing pipelined architectures with residue amplification, Successive-Approximation Register (SAR) ADCs as the sub-ADC and power efficient Ring Amplifier based...

  • Single-Ended Techniques for Delta-Sigma Modulators

    Creator:
    Lee, Calvin Y.
    Abstract:
    This work presents a high-resolution Delta-Sigma ADC which combines the use of the pseudo-pseudo-differential noise filtering technique with single-ended ring amplifier based integrators. The pseudo-pseudo-differential noise filtering technique utilizes single-ended circuits while maintaining the even-order rejection found in fully-differential structures which alleviates, in the active analog blocks, the need for...
