Abstract
In a drive circuit provided with a driver, signal quality is improved. There is provided a drive circuit that includes a driver, an amplitude adjuster, and a common voltage adjuster. In this drive circuit, the driver outputs a differential signal. The amplitude adjuster generates, from one of a pair of voltages, the other of the pair of voltages, and supplies the other of the pair of voltages to one of a power supply terminal and a ground terminal of the driver. The common voltage adjuster generates the one of the pair of voltages from an intermediate voltage between the pair of voltages, and supplies the one of the pair of voltages to the other of the power supply terminal and the ground terminal.
