Hi,
at RF, decoupling capacitor placement and design can be very important. The supply line connecting the supply to the circuit has some inductance and resistance which prevents it from reacting quickly to fast changes in the current drawn from the supply. Having a decoupling capacitor close to the circuit provides a large well of electrons for the circuit to draw from during transients.
I think there is a document on this website somewhere with a good discussion on supply decoupling. BTW, I said at RF because that's what I mostly work on, but I'm sure in other areas it is also very important.
regards, Aaron
