Decoupling capacitors

Download and install TINA-TI, the preferred simulator used exclusively with TI Precision Labs.

This video looks at factors impacting the impedance of the decoupling
network, such as PCB trace length, via selection, and capacitor parasitics. 
The video also covers how current flows relative to the decoupling network
and associated power and ground planes.  Let’s start by looking at the
decoupling network from a transient and AC impedance perspective.

The presentations from TI are always first class. Having some of the smartest people on hand to interact with makes this is a dream company to work for. That alone makes this one of the top 5 companies to work for.

At 7:57 the presenter says that typical ESL of capacitors is about 200 nH, and thus the traces inductance to a decoupling capacitor can "easily be a dominant factor". But the table shows inductance between 1 and 15 nH, nearly 2 orders of magnitude smaller than the ESL of a capacitor. Why does he say then that the trace inductance can be dominant, when the ESL is so much larger? Am I missing something?

Thank you for knowledge transfer. Looking more videos.

Great video! Do you think filled vias make a difference?

When you say parasitic capacitance at 11:00, what parasitic?

Hi Art,

That is a great presentation! That is a solid starting ground (no pun intended) for a "lowish" frequency circuit layout. Thank you for sharing!

Particularly interesting that using multiple decoupling capacitors of different values can be detrimental due to same ESL. That really was a good practice back then when SMD was not widely available, so the usual 100pf || 1nF || 10nF...
