Abstract
A current corresponding to the difference between an input signal voltage and an output signal voltage is generated as an amplification acceleration current. The amplification acceleration current is sent to an output node of a current mirror, which drives a transistor in an output amplifier stage, and therefore added to a current to drive the transistor in the output amplifier stage.
