  • Area-optimum rapid acquisition cellular multi-protocol digital DC offset correction scheme
    Patent number: 6606359
    Abstract: A digital DC offset correction circuit (68) provides DC offset correction within a receiver (50) using an area-optimum, rapid acquisition cellular multi-protocol digital dc offset correction scheme. The digital DC offset correction circuit (68) includes an integrator (90), a low pass filter (92), a decimator (94), a digital to analog converter codeword clamp (96), and a digital to analog converter (98).

  • DC offset correction scheme for wireless receivers
    Patent number: 6560447
    Abstract: A DC offset correction circuit (68) provides DC offset correction within a receiver (50) for receiving and processing a radio frequency signal (28) within a radio communication system (30). The DC offset correction circuit (68) includes a feedback loop (88) for shifting a digital signal (80) by a programmable amount; and a coarse DC offset correction path (104) coupled to the feedback loop (88) for performing coarse DC offset correction.
