SEMICONDUCTOR INTEGRATED CIRCUIT CAPABLE OF AUTONOMOUSLY ADJUSTING OUTPUT IMPEDANCE
摘要：
A semiconductor integrated circuit includes an output driver, a replica driver, a replica resistor, and an impedance adjustment circuit. The output driver is configured to be capable of changing current driving capability. The replica driver is configured to be capable of changing current driving capability. The replica resistor is connected to an output of the replica driver. The impedance adjustment circuit is configured to adjust the current driving capability of the output driver and the replica driver, based on an output voltage of the replica driver. In addition, the output driver, the replica driver, the replica resistor, and the impedance adjustment circuit are mounted in an integrated circuit package.
