Abstract
A signal modulation circuit includes a feedback circuit configured to generate the feedback signal for feeding back a drive signal from a driver circuit to an input signal. The feedback circuit includes at least first and second resistors connected together in series, the second resistor having a higher resistance value than that of the first resistor. One end of the first resistor is connected to a subtracter, and one end of the second resistor is connected to the driver circuit. A first line distance as the line length between one end of the first resistor and the subtracter and a second line distance as the line length between one end of the second resistor and the driver circuit are set shorter than a third line distance as the line length between the other end of the first resistor and the other end of the second resistor.
