Hi Experts.
Thank you for your support.
and I'm getting very valuable informations on this site and your advices.
This question is same project of my last thread.
but unlike that thread,
I also have to make voltage source (buffer) to apply sinewave to DUT.
The Target is 3Apeak, and the frequency is 20~1MHz same as last thread.
So I'm try to use 8~12ea THS3491 like below. which is described on one of your document.
But I can't use big Rs, I want to reduce it as possible as I can.
because if Rs is too big than DUT, Most of the voltage would be applied to Rs. not DUT.
So If possible, the equivalent Rs of all parallel Amps should be smaller than 100mohm.
Being such, the Rs of each amp should be 1.2ohm or smaller than that.
Could you give me a advice it would be possible or not?
I really appreciate your support.
Thank you
