Claim:
1. An amplifier applicable to an intra-band non-contiguous carrier aggregation (NCCA) band, the NCCA band including at least a primary component carrier (PCC) channel and a secondary component carrier (SCC) channel not adjacent to each other, the amplifier comprising: a first amplifier circuit, arranged to receive a first input signal and generate a first output signal for undergoing down-conversion of one of the PCC channel and the SCC channel; and a second amplifier circuit, arranged to receive at least one second input signal and generate a second output signal for undergoing down-conversion of another of the PCC channel and the SCC channel; wherein the at least one second input signal received by the second amplifier circuit is provided by the first amplifier circuit according to the first input signal, and comprises a derivative of the first input signal.
