DOWN CONVERTER WITH OFFSET CANCELLATION AND METHODS FOR USE THEREWITH
摘要:
A down conversion module includes a mixer operable to down convert an amplified receive signal from a low noise amplifier, based on a local oscillation, to produce a mixer output signal. A mixer load section is operable to produce a down converted signal from mixer output at an output of the mixer load section. A direct current (DC) offset cancellation module is operable to measure a DC offset at the output of the mixer load section, to generate cancellation currents and to combine the cancellation currents with the mixer output signal to provide DC offset cancellation.
