DRIVER CIRCUIT AND ADJUSTMENT METHOD THEREFOR |
摘要 |
A driver circuit includes an output section; a voltage-dividing section configured to divide a first voltage at a coupling point between the output section and a termination resistor; a comparison section configured to compare a voltage difference with one of the first voltage and a second voltage, the voltage difference being a difference between the second voltage at a coupling point between the termination resistor and a transmission path and a third voltage output from the voltage-dividing section; and an adjustment section configured to adjust a voltage division ratio of the voltage-dividing section on the basis of the comparison result obtained in the comparison section.
