ABSTRACT:
A device and method for adjusting an impedance of an output driver of an integrated circuit; the method includes: (i) receiving, by the output driver, a first square wave signal that should be driven by the output driver to provide a second signal; (ii) monitoring, by a monitoring circuit included in the integrated circuit, the second signal during an output driver transient period resulting from a first square wave signal transient to provide a monitoring result; (iii) determining whether to adjust the impedance of the output driver in response to the monitoring result; and (iv) adjusting the impedance of the output driver in response to the determination.
