PCB相关  PCB设计问题集锦

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 ...

电源技术  电源工程师-电路设计中的英雄

Abstract: We don&#39;t expect manufacturers to produce clothes that in one size that fits everyone. In thesame way, one ESD component can&#39;t solve all issues&mdash;each application has different ESD requirements.Knowing that "one size fits all" cannot apply to power design, the power designer, ...

电源技术  使用5V电源的高分辨率视频解决方案

&nbsp; Video cable driver amplifi er output stages traditionallyrequire a supply voltage of at least 6V in order to providethe required output swing. This requirement is usuallymet with 5V supplies by adding a boost regulator or asmall local negative rail, say via the popular LT&reg;1983-3.Such ...
