Abstract:
The present invention discloses a current-matching circuit including a hierarchical tree structure having two or more levels, each of which includes multiple matching devices, wherein each matching device at a preceding level corresponds to a predetermined number of matching devices at a next level. Respective matching devices at a last level control currents in respective current channels; the channels of the same group are matched with one another in current.
