Hi all.

can someone help me how to find gain of an differential amplifier in cadence.. i mean what are going to be my virtuso parameters.. and how to plot graph, and how to measure gain ??

thanks,
sreel
 

DC sweep the input voltage and look at its derivative.
 

gain is Vout/Vin rite !! then u dnt need Vout ?? can u explain lil bit more, i need to get a gain of 25 how to get tht ?? where i need to take my output parameters

thanks,
Sreel
 

Sorry, I meant look at the derivative of the output voltage.
