  • 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...

  • 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...

  • 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...

  • A 10 bit algorithmic A/D converter for a biosensor

    Creator:
    Rengachari, Thirumalai
    Abstract:
    This thesis presents a novel algorithmic A/D converter to be used in a biosensor. The converter is capable of a conversion rate of 1.5 bits/phase and hence the required conversion time is reduced. The proposed architecture is analyzed for non-ideal effects and compared with existing algorithmic A/D architectures. The converter...

  • 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...

  • Design techniques for clocking high performance signaling systems

    Creator:
    Hanumolu, Pavan Kumar
    Abstract:
    Scaling of CMOS technology has progressed relentlessly for the past several decades. In order for this unprecedented scaling to benefit the performance of large digital systems, the communication bandwidth between integrated circuits (ICs) must scale accordingly. However, interconnect technology does not scale as aggressively, making communication between chips the major...

  • An efficient switched capacitor buck-boost voltage regulator using delta-sigma control loop

    Creator:
    Rao, Arun
    Abstract:
    Voltage converters or charge pumps find their use in many circuits. They are extensively used in hand held devices as cell phones, pagers, PDA's and laptops. Some of the important issues relating to design of voltage regulators for handheld devices are size, efficiency and noise. Another important factor to be...

  • Design techniques for low-voltage analog-to-digital converter

    Creator:
    Chang, Dong-Young
    Abstract:
    Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low-voltage conditions. There are several well-known techniques to bypass the problem. These approaches include: (1)...

    Abstract:
    Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor (SC) circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low voltage conditions. There exist three techniques to solve the problem, but with their...
