摘要：
A current mirror circuit including at least one current bank transistor coupled to a cascade transistor. The cascade transistor further coupled to a current mirror input. A current-controlled current source operable for both receiving a differential current from said current mirror input and for producing a charging current for charging a gate of the at least one current bank transistor in order to null the differential current.
