US Patent 9639102 Predictive current sensing

A system and method are provided for estimating current. A current source is configured to generate a current and a pulsed sense enable signal is generated. An estimate of the current is generated and the estimate of the current is updated based on a first signal that is configured to couple the current source to an electric power supply and a second signal that is configured to couple the current source to aloud. A system includes the current source and a current prediction unit. The current source is configured to generate a current. The current prediction unit is coupled the current source and is configured to generate the estimate of the current and update the estimate of the current based on the first signal and the second signal.
