这是发布在SIJ(信号完整性杂志)2020年1月份的封面文章,作者为大名鼎鼎的信号完整性专家Eric Bogatin。 看很多的设计中,电源的去耦都使用3个不同值的电容10uF、1uF、0.1uF并联在一起使用,为什么?从电路的角度不就是11.1uF么?为啥要放三个?0.1uF几乎遍布所有 ...
You are designing your latest sub-system and somebody tells you to place as many 100 nF decoupling capacitors as you can, as close as physically possible to all the integrated circuits, just like we ...
The rule of thumb to use a 0.1-µF capacitor on the power pin of a semiconductor device is rapidly fading away. Semiconductor products of today have multiple power pins and voltages. But, it is more ...
Because of their high ESL compared to ceramic, tantalum capacitors are not the optimum choice for high frequency decoupling. Paralleling tantalum capacitors for bulk capacitance and ceramic for high ...
Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...
