  • Methods and apparatus for calibration of automatic gain control in broadcast tuners
    Patent number: 7853229
    Abstract: In one aspect, a calibration component configured to calibrate an automatic gain controller (AGC) for use in a tuner configured to isolate a selected channel from a multi-channel broadcast signal, the tuner implemented substantially on two chips, a first chip comprising a radio frequency (RF) integrated circuit adapted for RF processing and a second chip comprising a digital integrated circuit adapted for digital processing is provided.
    Type: Grant

  • ?? analog to digital converter system with automatic gain control responsive to out-of-band interferers
    Patent number: 7439890
    Abstract: An improved ?? analog to digital converter system with automatic gain control response to out-of-band interferers including a ?? multibit analog to digital converter responsive to an analog input for providing a digital output including the in-band signal and out-of-band interferers and quantization noise and a signal peak estimator circuit responsive to the out-of-band interferers for generating a gain control signal for adjusting the gain of a variable gain element which may be an independent element such as a variable gain amplifier or it may be the analog to digital converter itself by virtue of its having an adjustable full-scale.
