Hello everyone,
I'm designing a chopper amplifier with input frequency is 2kHz and F_chop = 2MHz.
Now I want to analysis stability of that circuit by finding its gain, phase.
the schematic of my circuit like as
After running simulation, I used the "main form" to observe the voltage gain result with input harmonic is 2k like as in this picture
the final result like this
That result make me confuse because it have a lot of result (-7, -6, -5, -4, ....., 4, 5, 6, 7). This difference from AC analysis which just have a plot with one line to observe voltage gain.
Could you please help me understand what mean of these line in the result plot?
which line is correctly result for the voltage gain with 2kHz input signal and 2MHz F_chop?
Thank everyone.
