Abstract:
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.

Claim (Index 1):
A receiver front-end system comprising:\n an antenna configured to receive a radio frequency signal; a transformer module coupled to the antenna and configured to convert the radio frequency signal to first differential signals; a mixer module coupled to the transformer module and configured to adjust frequencies of the first differential signals in order to generate second differential signals; a common-mode feedback module coupled to the mixer module and configured to reduce a common error of the second differential signals in order to generate third differential signals according to a reference signal; an amplifier module coupled to the common-mode feedback module and configured to amplify the third differential signals to generate amplified third differential signals; and a bias module coupled to the amplifier module and the common-mode feedback module and configured to generate the reference signal to the common-mode feedback module according to the amplified third differential signals; wherein the first differential signals, the second differential signals, and the third differential signals are unbalanced, a common signal of the first differential signals is disturbed by the common error, and a common signal of the third differential signals approaches to the reference signal.
