    Abstract: In a semiconductor device, a first amplifier block operates in a holding mode for a first period to output a first tap voltage based on a first tap input voltage and an offset of a first gamma amplifier sampled. A second amplifier block operates in the holding mode during the first period to output a second tap voltage based on a second tap input voltage and an offset of a second gamma amplifier sampled. A third amplifier block operates in a sampling mode during the first period to sample an offset of a third gamma amplifier based on the second tap input voltage.; Input terminal switches divide the first and second tap input voltages to the first to third amplifier blocks, and output terminal switches transmit the first tap voltage and the second tap voltage from at least some of the first to third amplifier block to a divider.
