Abstract
An amplifier includes an amplifier circuit and a gain adjusting circuit. The amplifier circuit has a design gain and a real gain and is configured to output an output signal according to an input signal and the real gain. The gain adjusting circuit is coupled to the amplifier circuit and is configured to receive the input signal to compare a voltage of the input signal with a first reference voltage, wherein when the voltage of the input signal exceeds the first reference voltage, the gain adjusting circuit increases the real gain of the amplifier circuit, so that the real gain approach the design gain.
