Device and method for current estimation |
摘要 |
A device and a method for estimating a current; the method includes: setting an impedance of a power gating circuit to a measurement value; wherein the power gating circuit selectively provides power to a circuit of an integrated circuit; measuring, during a measurement period, an electrical parameter indicative of a current that flows through the power gating circuit; and reducing an impedance of the power gating circuit to a power provision value to reduce a voltage developed on the power gating circuit during a power provision period. |
