摘要： A driver for shaping a drive signal includes a pre-emphasis circuit, an offset adjustment circuit, and an amplifier. The pre-emphasis circuit symmetrically emphasizes a rising edge portion and a falling edge portion of the drive signal. The offset adjustment circuit applies a direct-current offset to the drive signal. The amplifier amplifies the drive signal with the direct-current offset adjusted by the adjustment circuit. The amplifier has an input-output characteristic with a nonlinear portion. The offset adjustment circuit adjusts the direct-current offset so that the drive signal is amplified in the nonlinear portion.
