  • Experimental verification of a mismatch-shaping DAC

    Creator:
    Hudson, William Forrest, 1971-
    Abstract:
    Delta-sigma data converters have gained popularity in both analog-to-digital and digital-to-analog converters (ADCs and DACs) due to their simplicity, high linearity and immunity to many analog circuit imperfections. These data converters include features such as oversampling, noise-shaping, and (historically) single-bit quantization. Single-bit converters are preferred for their inherent linearity. This...

  • Lowpass and bandpass current-mode delta-sigma DACs employing mismatch-shaping

    Creator:
    Shui, Tao, 1969-
    Abstract:
    Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). These oversampled data converters have several advantages over conventional Nyquist-rate converters, including an insensitivity to many analog component imperfections, a simpler antialiasing filter and reduced accuracy requirements in the sample and hold....

  • Multi-bit delta-sigma switched-capacitor DACs employing element-mismatch-shaping

    Creator:
    Lin, Haiqing
    Abstract:
    Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters (ADCs and DACs). Most delta-sigma modulators in production today employ single-bit quantization because a 1-bit DAC is inherently linear, whereas a multi-bit DAC is not. Were it not for this drawback, the use of multi-bit...

  • Improving a sampled-data circuit simulator for Delta-Sigma modulator design

    Creator:
    Hayward, Roger D.
    Abstract:
    Delta-Sigma Modulator-based Analog-to-Digital converter design is an active area of research. New topologies require extensive simulations to verify their performance. A series of improvements were made to an existing circuit simulation package in order to speed the simulation process for the designer. Various examples of these improvements are presented in...
