The invention provides a low noise amplifier. The low noise amplifier includes a first transistor, a second transistor, and a first resistor. The first transistor has a gate to receiving a radio frequency input signal, wherein the source of the first transistor is coupled to a ground voltage. The second transistor has a drain to output a radio frequency output signal, wherein the gate of the second transistor is coupled to a first reference voltage. The first resistor is coupled between the drain of the first transistor and the source of the second transistor.
