Title: CMOS Operational Amplifier
Post by midou on Jul 2^nd, 2008, 1:06am

hey,

I want to know the total input noise of the CMOS Operational Amplifier..

so, what simulation must be done..?

(I use the "Spectre" simulator--CADENCE tool)

:) ;)

Use the "noise" simulation. Just set the start and stop frequency, and select the output nodes and the input voltage source. If you want total nosie in V², you need to integrate over frequency.

BTW you don't need to post your question more than once next time...

cheers,
