Hi everyone,
I'm having a problem with an amplifier, because I'm having a simulated maximum THD1 of 0.04% at 4 ohm (~ 1W to 100W), and a maximum THD20 of almost 0.5% (typical levels 0.2-0.3%) which is terribly high, I don't know what it's causing this, but I suspect that the problem is the Cmiller capacitor that is too high, and is decreasing the slew rate, but I can't lower it and keeping the phase margin.
Can someone help me here?
Thank you very much for your concern,
Best regards,
Daniel Almeida
