ABSTRACT:
A low noise amplifier including an amplifier kernel circuit and a DC bias unit is provided. The amplifier kernel circuit is used for receiving a single input signal or a differential input signal so as to output a differential output signal. The DC bias unit is coupled to the amplifier kernel circuit, and is used for processing a signal source to generate the single input signal or the differential input signal according to its circuit configuration.
