I have plotted Sopt and Zopt on the graph by using the Zopt block from S paramter-simulation palette.
At 61Ghz If i look at the values of Zopt, they are 55+41j .
So if i change my Zs tp 55+41j- It would be good for impedence matching at the input for low noise figure. I should get a smaller value of noise figure on the input side . right?
But thats not happening at the moment. When i change the value of Zs to match the value of Zopt . and simulated my circuit . I dont get the results what i wanted.
MY zopt also changes by changing Zs.
