decoupling
The smallest capacitors are faster; thus, they can react fastest. The goal of the smallest capacitor is to "filter" higher frequency noise. (This one is the one where I struggle.) From what I''ve read, the reason to place the smallest closest is that high frequencies are affected by the length of the trace more than smaller frequencies.

6.1.2: Capacitance and Capacitors
A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as ...
