Device and method for compensating for voltage drops

摘要

A device that includes at least one current consuming component. The device is characterized by including a compensation circuit adapted to compare between a voltage level at a sensing point within an integrated circuit and between a reference voltage derived from a voltage peak level at the sensing point; and to selectively increase the voltage at the sensing point in response to the comparison. A method for compensating for voltage drops in an integrated circuit, the method includes providing at least a first supply voltage to an integrated circuit; the method is characterized by including: comparing between a voltage level at a sensing point within an integrated circuit to a reference voltage derived from a voltage peak level at the sensing point; and selectively increasing the voltage at the sensing point in response to the comparison.

1. A method comprising:
providing at least a first supply voltage to an integrated circuit (IC); determining a first peak voltage level at a first sensing point of the IC over a period of time; determining a first voltage level at the first sensing point of the IC at a first time; comparing information based on the first voltage level to information based on the first peak voltage level to determine a first voltage drop has occurred at the first sensing point; and selectively increasing the voltage at the first sensing point to compensate for the first voltage drop in response to the comparison.
