Understanding Delta-Sigma Data Converters

Delta-Sigma(Σ-Δ)_AD转换器原理及PSPICE仿真

为了深入理解Delta-Sigma A／D转换器的工作原理，合理地使用这类A／D转换器产品，或者用FPGA实现自己的Delta-Sigma A／D转换器设计。采用PSpice仿真软件进行模拟仿真的方法，对不同幅度的输入信号进行了一阶Delta-Sigma A／D转换器仿真实验，获得了与理论相一致的结果。通过对元件的参数扫描仿真为实际电路设计中元件的选择提供了实验依据。仿真实验过程完整，易于重复，与纯数学推导相比，仿真具有直观的特点。

模数转换器(ADC)在信号处理中起了一个非常重要的作用。在数字音频、数字电视、图像编码及频率合成等领域需要大量的数据转换器。由于超大规模集成电路的尺寸和偏压不断减小，模拟器件的精度和动态范围也不断降低，对于实现高分辨率的ADC是一种挑战。高阶多位Delta-sigma ADC由于不需要采样保持电路，电路规模小，可以实现较高的分辨率，因此在实际中得到广泛的应用。Delta-sigma ADC采用过采样技术和噪声整形技术相结合，对量

实现空间电压矢量方法的高级简单配置 Delta-Sigma 调制三相逆变器。 为了小型化和提高各种类型的开关模式逆变器和转换器的性能，研究人员迄今已作出巨大努力。 在这些开关节点转换器中，通常使用电压调节的脉宽调制 (PWM) 技术。 在使用PWM处理方案的情况下，噪声峰值出现在整个载波频率处。 这对转换器附近的电子信息、电信、消费和医疗设备造成不良影响。 相反，在将 delta-sigma 调制方案应用于开关电源转换器的情况下，在高频段中不会出现噪声峰值。 在本文中，提出并评估了一种引入空间电压矢量调制方案的先进三相delta-sigma 调制逆变器。虽然所提出的调制逆变器由简单的配置组成，但所提出的方案可以有效地抑制噪声水平，并且开关操作次数少。

本文设计了一个用在ADC(ADC)中的3阶8级量化的delta-sigma调制器(DSM)。该调制器的过采样率128，信号带宽32．8kHz，分辨率16位。在设计噪声传输函数(NTF)时采用前馈方式实现极点和局部反馈实现零点，从而优化了输出信噪比，通过这些方法提高动态范围(DR)，降低量化噪声。这个DSMl的峰值信噪比可以达到145db以上。最后本文给出了这个DSM的MATLAB仿真模型及仿真结果，在此模型基础上编写电路模块verilog程序及进行行为级建模。

Book Description Learn how to harness the power of delta-sigma data converters Understanding Delta-Sigma Data Converters brings readers a clear understanding of the principles of delta-sigma (ΔΣ) converter operation—analog to digital and digital to analog. It introduces the best computer-aided analysis and design techniques available. With an understanding of the great versatility of the ΔΣ converter, readers can apply their new knowledge to a wide variety of applications, including digital telephony, digital audio, wireless and wired communications, medical electronics, and industrial and scientific instrumentation. The authors make the material accessible to all design engineers by focusing on developing an understanding of the physical operation rather than getting mired in complex mathematical treatments and derivations. Written for entry-level readers, the publication has a natural flow that begins with basic concepts, enabling the readers to develop a solid foundation for the book's more complex material. The text, therefore, starts with a general introduction to the ΔΣ converter, including a brief historical overview to place it in context. Next, the publication introduces the first-order ΔΣ modulator, covering oversampling, noise-shaping, decimation filtering and other key concepts. Then, using the first-order modulator as a foundation, second and higher-order modulators are presented and analyzed. Finally, the authors delve into implementation considerations and present several design examples using the Delta-Sigma Toolbox. Everything needed to facilitate quick comprehension and help readers apply their newly learned principles is provided: Simplified methods to understand complicated concepts such as spectral estimation and switched noise References that lead to in-depth analysis of specialized topics Figures and charts that illustrate complex design issues Conclusion section at the end of each chapter that highlights the key points Reference manual for the Delta-Sigma Toolbox, along with numerous practical examples that illustrate the use of the Toolbox This is essential reading for all design engineers who want to learn and fully harness the powerful capabilities of ΔΣ data converters. Upper-level undergraduates and graduate students will find the book's logical organization and clear style, coupled with numerous practical examples, a great entry into the field.
