Abstract: An integrated circuit includes: an amplifier circuit including a first inverter and a second inverter to amplify a voltage difference between a first line and a second line; a replica amplifier circuit including a first replica inverter having an input terminal and an output terminal which are coupled to a second replica line and replicating the first inverter, and that includes a second replica inverter having an input terminal and an output terminal which are coupled to a first replica line and replicating the second inverter; and a current control circuit suitable for controlling an amount of a current sourced to the replica amplifier circuit and an amount of a current sunken from the replica amplifier circuit based on comparison of an average level between a voltage of the first replica line and a voltage of the second replica line with a level of a target voltage.
