I am do an assignment about the LNA simulation.
V3/V4 is vsin from analogLib. I set the DC voltage to 1.25V and the Amplitude to 1uV. Freq 1 = 1G, Freq2 = 1.001G. The phases of V3/V4 are 0 and 180, respectively. Then try to run the trans analysis. From my understanding, voltage of VG1 should be 1.25V ± 1uV. But from the simulation it is from 250mV to 2.23V. I don't know why?
Can anyone give me any indication? Thanks
