Method and device for processing the DC offset of a radiofrequency reception subsystem

摘要

A method may compensate for direct current (DC) offset in a radio frequency reception device. The method may include partitioning an analog portion of the reception device into a plurality of zones, for each zone, calibrating initial DC offset compensation to be applied within an operating range of a respective zone, the operating range of the other zones being limited to a threshold operating range, and determining DC offset compensation to be applied to the reception device throughout the operating range based on the basic DC offset compensations.
