技术教程 共模电感应用说明
一般在选用共模电感的时候重点注意以下几个参数：
1) Impedance 表示器件在100MHz 时最大的阻抗值。一般在应用共模电感时候，
都是以此值作为选用的重点参考。
2) Rated Current 表示器件应用时候的最大额定电流。在选用的时候，这个参
数作为此重点，电路工作电流一定要小于器件额定工作电流，不然容易烧毁器件。
3) 至于 ...
模拟电子 了解模数转换器的噪声、ENOB
Abstract: Specifications such as noise, effective number of bits (ENOB), effective resolution, and noise-free resolution inlarge part define how accurate an ADC really is. Consequently, understanding the performance metrics related to noise isone of the most difficult aspects of transitioning from ...
