Apparatus and method for enhancing DC offset correction speed of a radio device |
摘要 |
The instant invention relates to an apparatus and method for enhancing DC offset correction speed of a radio device. On the exemplary, the apparatus includes one or two-stage signal-processing units and a controller. Each signal-processing unit has a baseband filter, a gain stage and a DC offset correction (DCOC) loop applied on the gain stage. A connection direction of an electrode terminal of a capacitor of the baseband filter is capable of being switched by the controller to process a pre-charge or a discharge phases thereby adjusting a bandwidth of the baseband filter to be either a normal operational bandwidth or wider than the normal operational bandwidth for rapidly setting time of the baseband filter. |
