Title (EN) REDUCING NON-LINEARITIES IN A DIFFERENTIAL RECEIVER PATH PRIOR TO A MIXER USING CALIBRATION
(FR) RÉDUCTION, PAR ÉTALONNAGE, DE NON-LINÉARITÉS, DANS UN CHEMIN DE RÉCEPTEUR DIFFÉRENTIEL, AVANT UN MÉLANGEUR
Abstract: front page image
(EN)A receiver for a wireless device is described. The receiver includes a low noise amplifier that includes differential inputs. The receiver also includes a mixer coupled to the low noise amplifier. The receiver further includes second-order intermodulation reduction circuitry coupled to a stage subsequent to the low noise amplifier. The second-order intermodulation reduction circuitry provides a biasing of the differential inputs.
(FR)Cette invention concerne un récepteur pour dispositif sans fil. Le récepteur comprend un amplificateur à faible bruit, à entrées différentielles. Le récepteur comprend également un mélangeur couplé à l'amplificateur à faible bruit. De plus, le récepteur comprend des circuits de réduction d'intermodulation de second ordre couplés à un étage subséquent à l'amplificateur à faible bruit. Ces circuits de réduction d'intermodulation de second ordre assurent une polarisation des entrées différentielles.
