Effect of decoupling capacitances on dynamic IR drop?
Well , infact i was searching for some docs on SI , and I came
across this question. I think I can give you a brief idea about
your query Decoupling means to disconnect- Decaps are used to
decouple one part of electrical n/w from other. noise caused by
other elements are bypassed to ground by this capacitor and thus it
nullify the effect. Dynamic IR is all abt the Ldi/dt effect of the
wires. The capacitor will try to cancel the inductive impedance
