Abstract
An apparatus includes a calibration circuit operative to produce an error signal indicative of an error associated with a current generator circuit generating a secondary current from a reference current. The secondary current is proportional to the reference current. The calibration circuit derives an adjustment value from the error signal and applies the adjustment value to the current generator circuit. Application of the adjustment value reduces a magnitude of the error signal.
