Abstract
The present invention relates to a current reference system comprising a selectively activatable high current reference circuit operable to generate a reference calibration circuit when activated and a low current calibrated reference current circuit operable to generate a reference current having a value based upon a control data. The system further comprises a control circuit operable to activate the selectively activatable high current reference circuit during a calibration period. The control circuit is further operable to vary a characteristic of the low current calibrated reference current circuit in a predetermined fashion while comparing another characteristic of the low current calibrated reference current circuit to a predetermined value. The control circuit then identifies a calibration condition based on the comparison, and generates the control data associated therewith.
