This class uses state-of-the-art CAD tools for circuit design and analysis. The final project is on the transistor-level design of a specific type of ADC or DAC. 进度安排 第一章 绪论(1学时) 第二章 行为级描述(3学时) 1. 抗混叠滤波 2. 采样保持电路 3. 量化器 4. 模拟重建滤波器 第...
CHAPTER 3 ADC and DAC Most of the signals directly encountered in science and engineering are continuous: light intensity that changes with distance; voltage that varies over time; a chemical reaction rate that depends on temperature, etc. Analog-to-Digital Conversion (ADC) and Digital-to-Analog...

Rev.A, 10/08, WK Page 1 of 12 MT-025 二进制和折叠型每级一位(串行)ADC 图2所示为用于执行单个二进制位转换的基本级,它由一个2倍增益放大器,一个比较器和 一个1位DAC(转换开关)组成.假设这是ADC的第一级.MSB就是输入的极性,通过比较 器进行检测,比较器还控制1位DAC.1位DAC的输出与2倍增益放大...
图5b示出一个包含伪随机数发生器驱动一个DAC的抖动噪声源。首先从ADC输入信号中减去这个抖动噪声,然后经过数字化添加到ADC输出端,因此使SNR无明显降低。但是,这种方法有一个固有的缺点,就是当抖动信号幅度增加时必须减小ADC输入信号的摆幅以防止过驱动ADC。应当注意的是,尽管这种方案改善了由ADC编码器非线性产生的...
So in fact you can use the DAC output at the same time as using the ADC inputs. TIP:You can use the DAC analogue output (Aout) since it has a track and hold amplifier. DAC Output Current There is a slight problem with the DAC output and that is its current output changes close to...
