商品描述

The Analog to Digital Converters represent one half of the link between the world we live in - analog - and the digital world of computers, which can handle the computations required in digital signal processing. These devices are mathematically very complex due to their nonlinear behavior and thus fairly difficult to analyze without the use of simulation tools. High Speed A/D Converters: Understanding Data Converters Through SPICE presents the subject from the practising engineer's point of view rather than from the academic's point of view. A practical approach is emphasized.

High Speed A/D Converters: Understanding Data Converters Through SPICE is intended as a learning tool by providing building blocks that can be stacked on top of each other to build higher order systems. The book provides a guide to understanding the various topologies used in A/D converters by suggesting simple methods for the blocks used in an A/D converter. The converters discussed throughout the book constitute a class of devices called undersampled or Nyquist converters.

The tools used in deriving the results presented are:
  • TopSpice™ by Penzar - a mixed mode SPICE simulator - version 5.90. The files included in Appendix A were written for this tool. However, most circuit files need only minor adjustments to be used on other SPICE simulators such as PSpice, Hspice, IS_Spice and Micro-Cap IV;
  • Mathcad 2000 - Professional by Mathsoft. This tool is very useful in performing FFT analysis as well as drawing some of the graphs. Again, the mathcad files are included to help the user analyze the data.

High Speed A/D Converters: Understanding Data Converters Through SPICE not only supplies the models for the A/D converters for SPICE program but also describes the physical reasons for the converter's performance.

商品描述(中文翻譯)

模擬轉數位轉換器（Analog to Digital Converters）代表著我們所處的世界（模擬）與能夠處理數位信號處理所需計算的電腦（數位）之間的連接。由於其非線性行為，這些設備在數學上非常複雜，因此在沒有模擬工具的情況下很難進行分析。《高速A/D轉換器：通過SPICE理解數據轉換器》從實踐工程師的角度而不是學術角度來呈現這個主題。強調實用方法。

《高速A/D轉換器：通過SPICE理解數據轉換器》旨在作為一個學習工具，提供可以堆疊在一起建立高階系統的基礎模塊。本書通過提供A/D轉換器中使用的模塊的簡單方法，指導讀者理解A/D轉換器中使用的各種拓撲結構。本書中討論的轉換器屬於一類稱為過取樣或奈奎斯特轉換器的設備。

本書使用的工具包括：
- Penzar的TopSpice™ - 一個混合模式SPICE模擬器 - 版本5.90。附錄A中的文件是為這個工具編寫的。然而，大多數電路文件只需要進行輕微調整即可在其他SPICE模擬器（如PSpice、Hspice、IS_Spice和Micro-Cap IV）上使用。
- Mathsoft的Mathcad 2000 - 專業版。這個工具在執行FFT分析和繪製一些圖形方面非常有用。同樣，mathcad文件包含在內，以幫助用戶分析數據。

《高速A/D轉換器：通過SPICE理解數據轉換器》不僅為SPICE程序提供A/D轉換器的模型，還描述了轉換器性能的物理原因。
