模拟电子 信号链和PLC是如何影响我们的生活
Abstract: It is incredible how many programmable logic controls (PLCs) around us make our modern life possible and pleasant.Machines in our homes heat and cool our air and water, as well as preserve and cook our food. This tutorial explains the importanceof PLCs, and describes how to choose compon ...
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 ...
Mentor Design Safe Verilog State Machine（Synplicity）
 
One of the strengths of Synplify is the Finite State Machine compiler. This is a powerfulfeature that not only has the ability to automatically detect state machines in the sourcecode, and implement them with either sequential, gray, or one-hot encoding. But alsoperform a reachability ana ...
电源技术 透过MOSFET电压电流最佳化控制传导性及辐射性EMI
經由改變外部閘極電阻(gate resistors)或增加一個跨在汲極(drain)和源極(source)的小電容來調整MOSFET的di/dt和dv/dt，去觀察它們如何對EMI產生影響。然後我們可了解到如何在效率和EMI之間取得平衡。我們拿一個有著單組輸出+12V/4.1A及初級側MOSFET AOTF11C60 (αMOSII/11A/600V/TO220F) 的50W電源轉接器(adapter)來做 ...
