Abstract
A compensation circuit includes a tail current source, an error amplifier; a compensation resistor, and a voltage-to-current converter circuit. The tail current source is configured to generate a tail current. The error amplifier is coupled to the tail current source and biased by the tail current. The compensation resistor is coupled to the error amplifier. The voltage-to-current converter circuit is coupled to the error amplifier. The compensation resistor is configured to vary in resistance responsive to a change in the tail current, or the voltage-to-current converter circuit is configured to vary in transconductance responsive to the change in the tail current.
