模拟电子 三电平变换器STATCOM空间矢量调制
This paper presents a space vector modulation(SVM)-based switching strategy for a three-level neutral point clamped (NPC) converter that is adapted as a STATCOM.
模拟电子 视频差分放大器带来低电压应用的多功能性
 
The LT®6552 is a specialized dual-differencing 75MHzoperational amplifier ideal for rejecting common modenoise as a video line receiver. The input pairs are designedto operate with equal but opposite large-signal differencesand provide exceptional high frequency commonmode rejection ( ...
模拟电子 数字集成电路设计Digital Integrated Circuit Design
 
This unique guide to designing digital VLSI circuits takes a top-down approach, reflecting the natureof the design process in industry. Starting with architecture design, the book explains the why andhow of digital design, using the physics that designers need to know, and no more.Coverin ...
模拟电子 DN454 单端至差分放大器设计技巧
 
A fully differential amplifi er is often used to converta single-ended signal to a differential signal, a designwhich requires three signifi cant considerations: theimpedance of the single-ended source must match thesingle-ended impedance of the differential amplifi er,the amplifi er&rsqu ...
模拟电子 STM32F10xxx设备中如何得到高精度ADC
The STM32F10xxx microcontroller family embeds up to three advanced 12-bit ADCs (depending on the device) with a conversion time down to 1 μs. A self-calibration feature is provided to enhance ADC accuracy versus environmental condition changes.
模拟电子 相敏检波电路鉴相特性的仿真研究
分析了调幅信号和载波信号之间的相位差与调制信号的极性的对应关系,得出了相敏检波电路输出电压的极性与调制信号的极性有对应关系的结论。为了验证相敏检波电路的这一特性,给出3 个电路方案,分别选用理想元件和实际元件,采用Multisim 对其进行仿真实验,直观形象地演示了相敏检波电路的鉴相特性,是传统的实际操作实验所不可 ...

PCB 被动组件的隐藏特性解析
传统上，EMC一直被视为「黑色魔术（black magic）」。其实，EMC是可以藉由数学公式来理解的。不过，纵使有数学分析方法可以利用，但那些数学方程式对实际的EMC电路设计而言，仍然太过复杂了。幸运的是，在大多数的实务工作中，工程师并不需要完全理解那些复杂的数学公式和存在于EMC规范中的学理 ...

PCB设计问题集锦
问：PCB图中各种字符往往容易叠加在一起，或者相距很近，当板子布得很密时，情况更加严重。当我用Verify Design进行检查时，会产生错误，但这种错误可以忽略。往往这种错误很多，有几百个，将其他更重要的错误淹没了，如何使Verify Design会略掉这种错误，或者在众多的错误中快速找到重要的错误。 答 ...
