Abstract
An integrated circuit device comprising at least one calibration module for calibrating an impedance of at least one on-die interconnect line driver in order to adaptively match an impedance between the at least one on-die interconnect line driver and at least one on-die interconnect line conjugated thereto. The at least one calibration module is arranged to receive an indication of an output signal of the at least one line driver, compare the received indication of an output signal to a reference signal and detect a presence or an absence of a voltage overshoot of the output signal of the at least one line driver, and upon detection of a presence or an absence of a voltage overshoot of the output signal of the at least one line driver, cause the adjustment of power supply of the at least one line driver, to be decreased or increased correspondingly.
