A method for improving sensitivity of a RF receiver and a RF receiver designed by the same are provided. The RF receiver, which receives a RF signal, comprises a sampling converting circuit, a decoding circuit, a frequency-hopping circuit, a constant current source and a ring oscillating circuit. The RF receiver outputs a frequency-hopping signal to the frequency-hopping circuit when the decoding circuit determines that the digital data converted from the RF signal is not equivalent to each of the internal preset data. The frequency-hopping circuit outputs a frequency-hopping current to the ring oscillating circuit to change a sampling clock of the RF receiver.
