Abstract
A system and method is provided for measuring a voltage drop at a node. In embodiments, a circuit includes an analog-to-digital converter, a current sink, and a controller. The input of the analog-to-digital converter and the input of the current sink is coupled to the node to be measured. A set point for the current sink is determined. The output of the analog-to-digital converter during the voltage drop is sampled. And a relative voltage drop value is computed by subtracting the sampled output of the analog-to-digital converter during the voltage drop from a sampled output of the analog-to-digital converter during a steady-state condition. The current sink operating at the set point during the steady-state condition and during the voltage drop.
