[Part 1 looks at the overall supply impedance seen by a component when the decoupling caps, the voltage regulator and the board traces are taken into account. Part 2 looks at how a real-world supply ...

Every project will need a few decoupling capacitors; our mini web server project has three ICs that require a total of 11. This can be an expensive part to buy in singles, so it’s crucial to ...

Figure 17. Capacitor impedance versus frequency The reason why the paralleling of capacitors in a distributed decoupling network works is because the total capacitance increases to , where n is the ...

In high-speed op-amp circuits, a parallel combination of two chip capacitors is recommended (Fig. 2a). A 1-µF tantalum and a 0.1-µF ceramic capacitor are typical.

As engineers, many of us probably learned bypassing/decoupling by observing what others have done; that is, just put a 0.1-µF ceramic capacitor on each IC power connection and be done with it.

The EC1005P features close-to-ideal parasitic parameters, allowing SoCs to operate with reduced voltage margining, reducing system power. The EC1005P ECAP leverages Empower’s high-performance and high ...
