Hi All,

I have an small confusion on Target impedance calculation for Decoupling.

As per my understanding peak transient current is = **0.5* maximum current**,( Ex: Imax= 1A current, then peak transient current = 0.5A).

But most of experts suggesting to consider **1.5* maximum current**, Hence peak transient current will be 1.5 A for given 1A maximum current.

Hence i have confusion that which one to follow!!! in Ztarget calculation.

So please if anybody give proper justification on above topic , It will be great help
