Abstract
A power amplifier includes an amplifying circuit, a feedback circuit and a grounding capacitor. The amplifier circuit includes at least a first transistor and a second transistor. A control terminal of the first transistor is configured to receive an input signal, a first terminal of the second transistor is coupled to the first transistor, and a second terminal of the second transistor is configured to generate an output signal. The feedback circuit is coupled to the control terminal of the first transistor and the second terminal of the second transistor. The ground capacitor is configured to couple the control terminal of the second transistor to ground. When a frequency of the input signal is between a first band and a second band, an amplification gain of the output signal relative to the input signal is substantially the same.
