  • Investigation of a noise-shaping accelerometer interface circuit for two-chip implementation

    Creator:
    Zechmann, Jacob W.
    Abstract:
    The world market for sensors is several hundred million dollars growing at an annual rate of 20 percent with accelerometers comprising 19 percent of the market. With an increasing market, a wide range of applications with varying degrees of resolution are in demand. Therefore, there is sufficient motivation for developing...

  • Low power high resolution data converter in digital CMOS technology

    Creator:
    Zheng, Zhiliang
    Abstract:
    The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also...

  • Active Noise Shaping Analog-to-Digital Data Converters

    Creator:
    Shi, Lukang
    Abstract:
    Successive-approximation-register (SAR) analog-to-digital converters are popular for medium accuracy, medium speed and low power applications, such as in biomedical applications. They have low latency and simple architecture compared with ΔΣ ADCs. This is because of SAR ADCs’ binary searching scheme. Furthermore, SAR ADCs can apply oversampling and noise shaping schemes...

  • High-speed switched-capacitor filters based on unity-gain buffers

    Creator:
    Bruneau, David
    Abstract:
    In this work a new voltage buffer, the drain-follower, achieves 300MHz band-width with 2pF load, a dc gain of 0.993V/V, 1mV offset voltage, -60 dB total harmonic distortion at 1.4Vpp output voltage and 6.5mW power dissipation from 5V supply. A unity-gain buffer switched-capacitor biquad filter has been implemented in 0.5μm...

  • Continuous time input pipeline ADCs

    Creator:
    Gubbins, David Patrick
    Abstract:
    Analog-to-digital converters (ADCs) convert analog continuous time signals into discrete time, digital format. One precondition that must be met for conventional nyquist rate ADCs is that the input signal must be suitably band-limited to an input bandwidth less than the nyquist frequency. This mandates expensive anti-alias filters which contribute to...

  • Low noise clocking for high speed serial links

    Creator:
    Brownlee, Merrick
    Abstract:
    As the functionality of digital chips continues to increase dramatically, chip- to-chip communication bandwidths must scale accordingly to avoid constraining the overall system performance. Therefore, high speed transceiver design has be- come an important research topic. In particular, the performance of the circuits that are responsible for timing accuracy are...

  • Generalized radix design techniques for low-power, low voltage pipelined and cyclic analog-digital converters

    Creator:
    Sharma, Vivek
    Abstract:
    This thesis proposes a novel technique for the design of pipelined and cyclic ADCs utilizing generalized radix gain stages. Several models have been proposed for the optimization of high performance pipelined ADCs by various researchers. This work builds upon them, using a simple but accurate model to estimate the optimal...

  • OP-AMP free SC biquad LPF and delta-sigma ADC

    Creator:
    Yoo, Kiseok
    Abstract:
    The objective of this work is to explore the feasibility of replacing conventional op-amps with inverters in switched-capacitor (SC) circuits. In order to verify the idea, a low-pass filter (LPF) and a second-order delta-sigma (∆Σ) analog-todigital converter (ADC) are designed in the 0.5-m CMOS technology. The low-pass filter structure is...

  • Fast opamp-free delta sigma modulator

    Creator:
    Thomas, Daniel E.
    Abstract:
    Switched-capacitor (SC) circuits are commonly used for analog signal processing because they can be used to realize precision filters and data converters on an integrated circuit (IC). However, for high speed applications SC circuit operating speeds are limited by the internally-compensated opamps found in SC integrators, a common building block...

    Wen, Jianping
    Abstract:
    The design of a switched capacitor successive approximation A/D converter is discussed in this thesis. This design adopts a novel capacitance mismatch error cancellation algorithm proposed in references [25, 27]. Detailed charge domain analysis is given in this thesis, which results in an improvement of the proposed algorithm by tracing...
