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 ...

Most ICs need to be decoupled from their power supply, usually with a 0.1uF capacitor between each power pin and ground. Decoupling is usually used to remove noise and to smooth power fluctuations.

This is the last of the “Yet more…” series. One final plot twist, a moderately satisfying ending, and my work here will be done. Until the sequel, that is… Let the op-amp do the pinging! Instead of ...

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 ...

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...
