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 ...

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 ...

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.

In “Know the sometimes-surprising interactions in modelling a capacitor-bypass network” (abbreviated to “Know the…” when referred to here), Tamara Schmitz of Intersil and I provided some simulation ...

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 ...

Deep-submicron systems-on-a-chip (SoCs) require a power-grid voltage drop of much less than 10% of VDD. Decoupling capacitors, or decaps, help achieve this goal by minimizing switching noise.

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 ...

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 ...
