Decoupling caps, PCB layout
The HIGH end of the frequency range has nothing (I repeat, nothing) to do with the capacitance of your capacitors: It is a function of the lead inductances of your capacitors and the number of capacitors (and their placement) in the network. The effective overall inductance is inversely proportional to N. Ten caps of 10 nF each are highly preferable over 1 cap of 100 nF. …
