I am doing decoupling analysis for one power net.How to calculate the Peak Transient current ?
Total input current combined for all the DDR IC is 792.00mA .
Got the answer
Maximum Transient Current:
A short-lived oscillation/decay in a system caused by a sudden change of voltage or current expressed as a function of time exponentially. The universal time constant formula is given by-
ITransient = Imax (1- e-t/τ)
e= eular’s number ≈ 2.7182818
e.g. t=1 sec , τ= 1
Itransient = Imax(1- e-1)= Imax* 0.6321 ≈ 0.5*Imax
I think this is correct .
