  • Low voltage switched capacitor circuits for lowpass and bandpass [delta sigma] converters

    Creator:
    Keskin, Mustafa
    Abstract:
    The most accurate method for performing analog signal processing in MOS (metal-oxide-semiconductor) integrated circuits is through the use of switched-capacitor circuits. A switched-capacitor circuit operates as a discrete-time signal processor. These circuits have been used in a variety of applications, such as filters, gain stages, voltage-controlled oscillators, and modulators. A...

  • 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)...

  • Low-power design techniques for low-voltage analog-to-digital converters

    Creator:
    Kim, Min Gyu
    Abstract:
    The demand for portable electronic systems and the continued down-scaling of device dimensions resulted in rapid improvement in the performance of integrated systems. Several low-voltage design techniques have been proposed to operate analog circuits with sub-1V supply. However, these techniques require higher power consumption to achieve large dynamic range while...

  • Design of low OSR, high precision analog-to-digital converters

    Creator:
    Rajaee, Omid
    Abstract:
    Advances in electronic systems have lead to the demand for high resolution, high bandwidth Analog-to-Digital Converters (ADCs). Oversampled ADCs are well- known for high accuracy applications since they benefit from noise shaping and they usually do not need highly accurate components. However, as a consequence of oversampling, they have limited...

  • High-performance delta-sigma analog-to-digital converters

    Creator:
    da Silva, Jose Barreiro
    Abstract:
    Multi-stage delta-sigma (ΔΣ) architectures, commonly known as MASH, are the preferred choice for analog-to-digital converters (ADCs) used in broadband communication applications, where high-resolution (above 14 bits) and high-bandwidth (several MHz) performances are required. Current state-of-the-art designs are capable of as much as 5-MS/s output data rates with 90-dB SNR. However,...

  • Design of a 1.8-V 14-bit [delta] - [sigma] A/D converter with 8X oversampling and 4 MHz Nyquist output rate

    Creator:
    Jiang, Ruoxin
    Abstract:
    In this dissertation, a new Δ∑ A/D converter is presented that is ideally suited for communication applications. It is based on a single-loop single-stage structure, which can realize a high maximum out-of-band quantization noise gain while maintaining stable operation and thus achieve 14-bit resolution at 8 times oversampling. A fifth-order...

  • Design techniques for low-voltage and low-power analog-to-digital converters

    Creator:
    Ahn, Gil Cho
    Abstract:
    With the ever-increasing demand for portable devices used in applications such as wireless communication, mobile computing, consumer electronics, etc., the scaling of the CMOS process to deep submicron dimensions becomes more important to achieve low-cost, low-power and high-performance digital systems. However, this downscaling also requires similar shrinking of the supply...

  • Automated synthesis of analog to digital conversion

    Creator:
    Weaver, Skyler
    Abstract:
    This thesis describes circuit architectures and techniques that facilitate the automatic synthesis and fabrication of analog-to-digital converters (ADCs). Since automated synthesis already exists for digital circuits and is part of the digital circuit design flow, this work demonstrates the feasibility of ADC synthesis with little or no modification to presently...

    Abstract:
    Enabled by continued device scaling in CMOS technology, more and more functions that were previously realized in separate chips are getting integrated on a single chip nowadays. Integration on silicon has opened the door to new portable wireless applications, and initiated a widespread use of these devices in our common...
