Abstract
One exemplary signal amplification circuit used for processing an input signal includes an input stage, a plurality of output stages, and a selecting stage. The input stage has an input node for receiving the input signal and an output node for outputting an intermediate signal. The output stages are coupled to a plurality of output ports of the signal amplification circuit, respectively. Each of the output stages generates a corresponding processed signal to a corresponding output port according to a gain and a signal derived from the intermediate signal of the input stage when enabled. The selecting stage is arranged for selectively coupling the output node of the input stage to at least one of the output stages.
