Decoupling Capacitor Calculations: What Size Should You Use
Here, you should use—at least—a 6 nF capacitor to compensate for a 0.5 V maximum voltage within 6 ns. Note that some guidelines would recommend using two 3 nF capacitors in parallel in this example as this would reduce ESR by a factor of 2, but this will also reduce ESL by a factor of 2, so the effect on damping is nil.
