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 ...

Any engineer knows that capacitors are a fundamental building block in RF/microwave systems. Bypass networks are one example—they require capacitors to bypass ac signals to ground. For such cases, ...

Usually marked onto the body of capacitors in the form of alphanumeric characters are the actual values of capacitance, voltage or tolerance. Although the capacitance value may be printed on the body ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

A basic requirement for all electronic circuits is the inclusion of bypass, or decoupling, capacitors. These devices reside across the positive supply to ground, as close as possible to the supply pin ...

Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual tolerance ranges afford. Precision matching of components from parts on hand ...
