Hi everyone,
I have a question about simulating the harmonic distortion of a fully differential amplifier in CLOSED LOOP.
I simulated the single output per transient analysis, transformed by FFT, then I can see large a power in the DC-part and signal frequency, small power by 2nd and 3rd harmonic distortion.
But the professor said, there should be no even-orderd harmonic distortion by fully differential design.
But in closed loop, I can only get the result.
Does anyone can answer me?
