Hi everyone,
I was using Miller dominant pole compensation and this kind of compensation, seems to produce high values of THD20 on the order of 0.0x %, so I decided to use something like TPC (two pole compensation) or TMC (Transient Miller Compensation), but I don't know much about this compensation methods, I don't know what to do to calculate the capacitors and the resistor. Using TPC I have overshoot on closed loop step response, using TMC I don't have, but it was told me that the amplifier could have other kinds of instabillities. I've made this designs using TMC, but I don't know if they are stable at high frequencies.
Can anyone with experience in this areas help me here.
Attached some attempts, possibly not good, using TMC comp.
PS: Some comments are from other amplifiers, output power for 4 ohm is on the order of 150, at much lower THD1.
Thank you all for your support,
Best regards,
Daniel Almeida
