Cycle-by-cycle current assessment using a current track threshold

A method for current assessment, comprising:

• comparing a current associated with a voltage regulator with a current track threshold to yield a state flag signal;
• detecting a duty cycle of the state flag signal;
• and
• adjusting the current track threshold to assess a first average of the current based on the duty cycle of the state flag signal, wherein the current track threshold is adjusted by an amount based on the duty cycle.

An apparatus for voltage regulation, comprising:

• a voltage regulator;
• and
• a current assessment circuit, comprising:
• a comparison circuit configured to compare a current associated with the voltage regulator with a current track threshold to yield a state flag signal;
• a duty cycle detection circuit configured to detect a duty cycle of the state flag signal;
• and
• a controller configured to adjust the current track threshold to assess a first average of the current based on the duty cycle of the state flag signal, wherein the current track threshold is adjusted by an amount based on the duty cycle.
