| Zusammenfassung: | A calibration circuit includes a reference resistor leg, a calibration code generation circuit, and an emphasis circuit. The reference resistor leg is coupled to an external reference resistor through a reference resistor node, and changes a voltage level of the reference resistor node based on a calibration code. The emphasis circuit accelerates a voltage level change of the reference resistor node based on the calibration code. |
