Systems and methods for self-calibration of a voltage regulator
Abstract:
A method may include causing a first test current to be delivered for a period of time from a phase of a voltage regulator to a load coupled to the voltage regulator, the phase configured to deliver electrical energy to the load. The method may also include measuring a first measured output current associated with the first test current. The method may further include causing a second test current to be delivered from the phase to the load for the period of time, the second test current differing from the first test current by a known offset. The method may additionally include measuring a second measured output current associated with the second test current. The method may also include calculating the respective gain and the respective offset of the phase based on the first measured output current, the second measured output current, the period of time, and the known offset.
