摘要： 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.

摘要： An integrated circuit, including: (i) a power gated circuit which power supply is shut down during a low-power period; (ii) a retention circuit, coupled to the power gated circuit during at least a portion of a non-low-power period, the retention circuit is adapted to store, during the low-power period, state information reflecting a state of the power gated circuit before the low-power period started; (iii) a first portion of the power grid, coupled to the retention circuit and to a first end of a power supply switch, adapted to provide to the retention circuit a supply voltage during the low-power period and during a non-low-power period; wherein the power supply switch is open during the low-power period and is closed during the non-low-power period; and (iv) a second portion of the power grid, coupled to a second end of the power supply switch and to the power gated circuit; adapted to supply a gated supply voltage to the power gated circuit during the non-low-power period. The first portion of the power grid is characterized by intrinsic capacitance that is larger that the intrinsic capacitance of the second portion of the power grid.
