Hello everybody !
I am simulating a mixer now,
LO = 1.4G RF = 1.5G
I found something unexpected:
in Pnoise simultion , I swept from 1k to 2G,and chose
"reference bandside "as "0 -1 -2 ". and the result is
showed in figure a~c.
but I think the noise should be mixed and added together ,
and the result should be ...(figure d).
I don't know why . I have refered to Cadence's design guide
and the "designers-guide" website, but I can't find my answers
thank you for helping me !~~~
