Does the Number of Bypass Capacitors for a Chip Matter?
Given the overall change (and not for the better with the spike in the total impedance) adding a second capacitor that is smaller has virtually no impact if it is placed outboard of the larger capacitor and a potentially negative effect if the smaller capacitor is placed inboard of the larger capacitor. Use a single bypass capacitor.
