1. 首先我们使用MATALB（candence）搭建sigma-delta ADC的模型，得到一串间隔不同的1、-1bit流。接着我们需要对这些数据流进行处理（滤除噪声、降低采样频率），具体可以看文献资料，下面会附上。 2. 大概说一下我的设计，采样频率256KHz,OSR=128,通过CIC（五级）抽取 ...

ADC — 模数转换器是连接模拟世界与数字世界的桥梁。说到这里，有些朋友会问，我们为什么需要模数转换？为什么需要ADC？ 依托值得信赖的供应商组合，我们可提供从关键元件到先进开发平台的全套解决方案，确保您的项目成功落地。无论您是正在开发全新的 ...

The requirement of effective analog to digital conversion and accuracy gives growth to converters. The sigma delta modulator have a salient feature of shaping the noise, such that noise reduces from ...

The delta-sigma ADC tackles the application demands of a slow analog signal that requires a high signal-to-noise-ratio (SNR) and wide dynamic range. But, the delta-sigma converter is not the only ...

This file type includes high resolution graphics and schematics. Delta-sigma analog-to-digital converters (ADCs) are fascinating—almost mythical in their ability to support low- to medium-speed and ...

The Analog-to-Digital Converter (ADC) is a key component in digital communications receive channels, and the correct choice of ADC is critical for optimizing system design. In this article, we discuss ...

Delta-sigma converters are ideal for converting signals over a wide range of frequencies from dc to several megahertz with very-high-resolution results. Figure 1 shows the basic topology, or core, of ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...
