| description | A method for enhancing linearity of the receiver front-end system includes receiving a radio frequency signal by an antenna, converting the radio frequency signal to first differential signals by a transformer module, adjusting frequencies of the first differential signals to generate second differential signals by a mixer module, detecting a common signal in order to reduce a common error of the second differential signals, and generating third differential signals according to a reference signal after the common error is reduced from the second differential signals. The first differential signals, the second differential signals, and the third differential signals are unbalanced. |
