the output of the error amplifier used in a dc-dc convertor is often coupled to a capacitor and a resistor.
it is said that the capacitor and the resistor in series are used to compensate

but how they works?

who can give me some references and guidence on this subject

thank you

they generates a zero to compensate pole, so the phase margin is improved
