Abstract
The present invention discloses a current-matching method comprising steps of: providing a plurality of current channels; grouping the plurality of current channels into W sets, each of which has Q channels; and matching the channels of the same set in current, where both W and Q are integers greater than or equal to 2. The present invention also discloses a current-matching circuit including 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.
