A chain-chopping current mirror and a method for stabilizing output currents are disclosed. The current mirror includes multiple output nodes, a bias source unit, multiple current mirroring units and multiple switch components. The bias source unit provides a reference bias according to the received current. Each of the current mirroring units outputs an output current according to the reference bias. The control terminal of each the switch component receives a clock signal and determines whether the first terminal thereof is coupled with the second terminal or the third terminal thereof according to the clock signal, wherein the first terminal of the i.sup.th switch component is coupled with the output terminal of the i.sup.th current mirroring unit, the second terminal thereof is coupled with the i.sup.th output node and the third terminal thereof is coupled with the (i+1).sup.th output node, where i is a natural number.
