Abstract

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.
