Abstract
A receiver performs DC offset correction by preliminarily using an unused LNA with a terminating resistance to determine a base level DC offset. Once the DC offset is determined, a DC offset correction may be calculated and applied to an active LNA output. When determining the DC offset, the active LNA is disabled.
