Dear Sir:
I am simulating output stage of class D amplifier as shown in attachment#1
-40dBc 2nd harmonic is observed at the output.
If we observe closer at the waveform (Hop) before LC filter:
(as shown in attachment #2)
overshot (>VDD=3V or <VSS=0V) are observed,
and in zommed-in pictures waveform above VDD
is not symmetric to that below VSS.
Please advise how to fix these problems?
Thanks in advance,
