Abstract
A system and method are provided for sensing current. A current source is configured to generate a current and a pulsed sense enable signal is generated. A sense voltage across a resistive sense mechanism is sampled according to the sense enable signal, where the sense voltage represents a measurement of the current. A system includes the current source and a current sensing unit. The current source is configured to generate a current. The current sensing unit is coupled the current source and is configured to generate a pulsed sense enable signal and sample the sense voltage across a resistive sense mechanism according to the pulsed sense enable signal.
