A trimming circuit is provided. The trimming circuit had at least a trimming cell, and each of the at least trimming cell includes three current paths and a fuse. A first one of the current paths is interrupted when a second one of the current paths is uninterrupted, and the first one of the current paths is uninterrupted when the second one of the current paths is interrupted. When a trimming control signal is at an enable state, a third one of the current paths is uninterrupted, such that the fuse is blown. Based on the status of the fuse, the trimming circuit is capable of trimming an output voltage or an output current of an electric apparatus.
