Sense Amplifier Questions...

[ipierre]

I am designing DC Circuits, have a question as below.

Please see the attached file.

Why to use NMOS connection? I know it can connect VBL directly without NMOS tr.
i am not sure is it good, and whether there was any concern.

Best regards,
iPierre

May be it needs some kind of isolation from the rest of the circuits

if you can post your SA circuit, i will know better
