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...
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...
Other schemes have been developed using larger amounts of dither noise to randomize the transfer function of the ADC. Figure 5b shows a dither-noise source comprising a pseudo-random-number generator driving a DAC. This signal is subtracted from the ADC input signal and then digitally added to...
DAC Channel OTHER PARAMETERS Output Offset 0 Input, Differential Line-output ±0.5 mV Output Common Mode Common Mode Level for OUTxP and OUTxM, AVDD = 1.8V Common Mode Level for OUTxP and OUTxM, AVDD = 3.3V 0.9 V 1.65 Common Mode Error DC Error in Common Mode Voltage ±10 mV Output...
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...
Added 'I' grade data for ADC and DAC Added 'I' grade part numbers and notes Added to feature description on front page and added part numbers fopr SNR and DNR (since they do not apply to 'I' grade devices.+ Reduced AVDD current to 26mA Increased Rvmid to 70K Added description of ...
Project is about reading and controlling using web interface, Bluetooth and buttons. Also all info will be on a 5-7" screen. I think I am going to add arduino boards(ATSAMD21G18 and ATmega32u4) to perform the decoding from the ADC and DAC(one for ADC and one for DAC) true i2c in...
