Abstract
This embodiment relates to a transmitter that has a structure to suppress an increase in device occupancy area on a semiconductor substrate. The transmitter includes an output driver, a duplication driver, a reference voltage generation unit, a first selection unit, a second selection unit, a comparison unit, and a control unit. The first selection unit selects a first or second test voltage outputted from a duplication driver in which a resistance value is set in cooperation with the output driver. The second selection unit selects a first or second reference voltage outputted from the reference voltage generation unit. The comparison unit compares magnitudes of the first test voltage and the first reference voltage during a first operation period and compares magnitudes of the second test voltage and the second reference voltage during a second operation period different from the first operation period.
