hi all, can any one please tell me after performing noise analysis in cadence, how to find output noise from "noise vs frequency" plot
 

Hi,

With calculator, you have VN2(), wich plot the squared noise vs frequency.
To obtain the output noise, just integrate over the desired bandwidth (iinteg), calculate the square-root, and here it is.
You shoul find the same value as output->print->noise summary (be careful of units)
 

thanks a lot gag, i came to know that my noise vs frequency plot was wrong.. so can u please tell me the procedure
