The invention discloses a power noise non-sensitive current mirror circuit, a chip and a communication terminal. The current mirror circuit comprises an input current unit; the input current unit is linked with one or more output current units in parallel; according to the ratio between the input current of an input current unit arranged in advance and a mirror current corresponding to the input current and output by an output current unit, the mirror current output by the output current unit in corresponding to the input current is controlled through an input current unit, noise components introduced by power source in the mirror current is eliminated, thus the current mirror circuit is not influenced by the high-frequency noise of the power source, the non-sensitive property of the powersource is realized.
