Abstract
A low noise amplifier circuit includes an input stage circuit, a first output stage circuit, and a second output stage circuit. The input stage circuit is configured to receive an input signal and to generate a bias signal. The first output stage circuit corresponding to a first wireless communication and is configured to be biased according to the bias signal and a first control signal, in order to generate a first output signal, in which the first control signal is for setting a first gain of the first output stage circuit. The second output stage circuit corresponding to a second wireless communication and is configured to be biased according to the bias signal and a second control signal, in order to generate a second output signal, in which the second control signal is for setting a second gain of the second output stage circuit.
