REDUCING NON-LINEARITIES IN A DIFFERENTIAL RECEIVER PATH PRIOR TO A MIXER USING CALIBRATION

摘要

The receiver is described for wireless devices. The receiver includes a low noise amplifier comprising a differential input. The receiver also includes a mixer coupled to said low noise amplifier. The receiver further includes a coupled second order intermodulation reduction circuit in the stage subsequent to the low-noise amplifier. The second-order intermodulation reduction circuit provides the biasing to the differential input.
