An amplifier structure is disclosed. The amplifier comprises a voltage source, a first amplifying unit and a second amplifying unit. The first amplifying unit is coupled to the voltage source to amplify a first input signal and a second input signal to generate a first amplified signal according to a bias current and a reference current. The second amplifying unit is coupled to the voltage source and the first amplifying unit to amplify the first input signal and the second input signal to generate a second amplified signal according to the bias current and the reference current, wherein the amplifier generates an output signal according to the first amplified signal and the second amplified signal.
