Title: HELP: OPAMP Offset-voltage reduction
Post by mulder on Nov 24^th, 2004, 4:41am

I'll design a opamp.The main specification is offset-voltage.
Only five PADs and die area is under 60000um2.
So, I can't use auto-zero and trimming methods.
Except normal opamp offset-voltage reduction methods,
are there any methods ?
Help me ,please.
Thanks

Depending on process used, it looks to me a plenty of space for auto-zero circuit.
