Abstract
An offset compensation scheme using a digital-to-analog converter (DAC) is disclosed. In some embodiments, a DAC is coupled to a circuit having an undesired current or voltage offset and is configured to at least in part compensate for the undesired current or voltage offset. For example, in some embodiments, the DAC injects current or voltage into the circuit that shifts a current or voltage of the circuit by an amount equal or similar in magnitude but opposite in polarity to a shift in the current or voltage of the circuit caused by the undesired current or voltage offset.
