Abstract
The present document describes an error amplification circuit for a voltage regulator. The error amplification circuit comprises a differential error amplifier having a first input for a feedback signal of the voltage regulator and having a second input for a reference signal, wherein the differential error amplifier is configured to provide an amplifier output current in dependence of the signals at the first input and at the second input. Furthermore the error amplification circuit comprises a current sensing unit configured to sense the amplifier output current to provide a sensed current, a processing unit configured to process the sensed current to provide a processed current, and an adjustment resistor which is arranged in series with the second input of the differential error amplifier and to which the processed current is applied.
