  • Test fixture characterization for high-frequency silicon substrate parasitic extraction

    Creator:
    Tabalujan, Andrew R.
    Abstract:
    At frequencies exceeding 1-2 GHz, the reactive nature of a silicon substrate must be accounted in the substrate network models used in substrate coupling simulation. High-frequency substrate models, containing reactive components, must be validated through high-frequency network analyzer measurements. Prior fabricated test fixtures have been modified to enable high-frequency (up...

  • Power Efficient Hybrid Architecture for High Resolution Analog-to-Digital Converters

    Creator:
    Zhang, Hui
    Abstract:
    Analog-to-digital converters (ADCs) are the key building block for sensor applications, such as wireless communications and digital electronics. These applications require ADCs to have medium to high accuracy (normally from 10-14 bits) and relatively low signal bandwidth (ranging from 100Hz-150kHz). Since these applications are often powered by batteries, high power...

  • A new data encoding scheme for equalization - Integrated Pulse Width Modulation (iPWM)

    Creator:
    Ramachandran, Ashwin
    Abstract:
    This work presents a new data encoding scheme: Integrated Pulse Width Modulation (iPWM) for equalizing lossy wireline channels with the aim of achieving energy efficient wireline communication. The proposed scheme is able to overcome the fundamental limitations imposed by Manchester and Pulse Width Modulation (PWM) encoding on high data rate...

  • High-Resolution mm-wave Digitally Controlled Oscillator in CMOS

    Creator:
    Wang, Yunqi
    Abstract:
    All-digital PLLs promise flexible and precise frequency modulation continous-wave(FMCW) radar signal signal for 77GHz radar applications. Such PLLs require digitally-controlled oscillators(DCO) with wide frequency tuning range and high resolution to address a range of applications and low phase noise requirements. In this thesis, novel resonator structures with ne capacitance/inductance switching...

  • Low-power high-linearity digital-to-analog converters

    Creator:
    Kuo, Ming-Hung
    Abstract:
    In this thesis work, a design of 14-bit, 20MS/s segmented digital-to-analog converter (DAC) is presented. The segmented DAC uses switched-capacitor configuration to implement 8 (LSB) + 6 (MSB) segmented architecture to achieve high performance for minimum area. The implemented LSB DAC is based on quasi-passive pipelined DAC that has been...

  • Design techniques for successive approximation register analog-to-digital converters

    Creator:
    Tong, Tao
    Abstract:
    Successive approximation register analog-to-digital converters (SAR ADCs) have been widely used for medium-speed, medium-resolution applications due to their excellent power efficiency and digital compatibility. Recently, SAR ADCs are also penetrating into the applications which have been earlier dominated by delta-sigma ADCs and pipeline ADCs. However, the resolution of SAR ADCs...

  • Highly-Integrated Low-Power RF Receivers for Distributed Sensing and IoT Devices

    Creator:
    Bialek, Hayden
    Abstract:
    Low-power receivers (RX) with 100$\mu W$-scale power consumption can enable several power/energy-constrained IoT applications. However, achieving sensitivity, interferer tolerance and wide operating range with low power presents a challenge for existing architectures, particularly those constrained to highly integrated solutions without high-Q off-chip components. Existing solutions rely heavily on high quality...

  • Digital Friendly Continuous-Time Delta-Sigma Analog-to-Digital Converters

    Creator:
    Maghami, Hamidreza
    Abstract:
    Conventional Delta-Sigma analog-to-digital converters (ADCs) utilize operational transconductance amplifiers (OTAs) in their loop filter implementation followed by multi-bit voltage domain quantizers. As CMOS integrated circuit technology scales to smaller geometries, the minimum transistor length and the intrinsic gain of the transistors decrease. Moreover, with process scaling the voltage headroom decreases...

  • 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...

  • Dynamic Error Calibration for Continuous-Time Delta-Sigma Modulator with Multi-GHz Sampling Rate

    Creator:
    He, Tao
    Abstract:
    Continuous-time ΔΣ modulators are widely used in cellular handsets due to their power efficiency and inherent anti-aliasing characteristics. To achieve demanding cellular bandwidth requirements while maintaining good power efficiency, multi-bit feedback is typically used. This approach provides benefits such as lower OSR, relaxed loop filter requirements, and reduced jitter sensitivity....
