Abstract
A mixer module includes a mixer, at least one DC offset circuit, a filter and a controller. The mixer mixes an input signal to generate a first signal. The at least one DC offset circuit generates a second signal based on the first signal. The filter filters out an AC portion of the second signal and generates a third signal according to a DC portion of the second signal. The controller controls the at least one DC offset circuit based on the third signal to reduce a DC portion of the first signal.
