Q: Question to power supply experts... by vball13.
I need to build a test bench for a chip. The chip has a block that when enabled draws 1.6A from a supply during 5nS. The problem is I need to put 20 chips on the test board. Any suggestions?

I think you may get away by using a decoupling cap. The cap should supply energy during the 5ns current spike.
Let's see if we can get the value right.
I = CdU/dt
I=1.6a , t=5nS , U=10mV (I think it's a reasonable number).
Then C = 1uF
