  • Mixer with calibration circuit and calibration method thereof
    Patent number: 9154080
    Abstract: A mixer with calibration circuit includes a first gm stage unit, a second gm stage unit, a first detecting unit, a second detecting unit, a comparison block, a control unit and a compensator. The first detecting unit and the second detecting unit are respectively connected to different gm stage unit, and the comparison block compares voltage signals of the first detecting unit and the second detecting unit. The control unit adjusts a current signal of the comparison block according to the comparative result of voltage signals of the first detecting unit and the second detecting unit. Further, the compensator adjusts the first gm stage unit and the second gm stage unit according to the current signal. Thereafter, the improvement of the LO leakage of the mixer can be achieved.
