Abstract
An extraction circuit is connected to an input path of an output amplifier. When the power is turned on, the extraction circuit extracts current on the basis of a difference between the normal rise of the supply voltage and a delayed supply voltage. Therefore, a steep rise in the input of the output amplifier when the power is turned on can be removed.
