ABSTRACT:
A semiconductor integrated circuit is provided comprising a first amplifier circuit which receives a first potential and then supplies a current to an output terminal; a second amplifier circuit which receives a second potential and then absorbs a current from the output terminal; and a control circuit which controls the second amplifier circuit so as to allow the second amplifier circuit to be activated subsequently to a predetermined period of time that elapses after the first amplifier circuit is activated.
