A resistance calibration method for a first resistor of a first module includes performing resistance calibration on a calibration unit of a second module, wherein the first module is connected to the second module via a pad coupled to the first resistor and the calibration unit is coupled to the pad; obtaining a resistance value of the calibration unit after the resistance calibration; and calibrating a resistance value of the first resistor according to the resistance value of the calibration unit.

Resistance calibration method and related calibration system

A method and an apparatus for self-calibration of a driving capability and a resistance of an on-die termination are provided. The apparatus includes an output interface physical layer (PHY) and a ring oscillator. The output interface PHY receives an operation voltage. The ring oscillator surrounds the output interface PHY to sense a work temperature or the operation voltage and accordingly outputs a sensing result. The driving capability or the resistance of the on-die termination of the output interface PHY is adjusted according to the sensing result.

Method and apparatus for self-calibrating driving capability and resistance of on-die termination

A circuit system periodically checks a system-environment monitor value, and then obtains a system-environment monitor value index corresponding to the system-environment monitor value in the environment-adjustment look-up table. Finally, the circuit system adjusts a signal delay time according to a delay adjustment value corresponding to the system-environment monitor value index.
