Abstract
Methods and systems for a DC offset correction loop for a mobile digital cellular television environment are disclosed. Aspects of one method may include removing at least a portion of a DC offset from output of an amplifier. The DC offset may be removed from a single stage amplifier, or from each stage of a N stage amplifier, where N may be an integer. The DC offset may be removed by using second differential signals generated from first differential signals, where the second differential signals may be communicated to inputs of the amplifier. The first differential signals may by a first circuit that integrates outputs of the amplifier. The first circuit may perform the integration using a variable corner frequency that may be adjusted by changing a resistance of at least one variable resistor in the first circuit.
