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
