Abstract: A frequency modulation (FM) radio receiver includes a processing unit that may generate a magnitude value corresponding to a signal strength of each of a plurality of digital samples of a received FM signal. The receiver also includes a noise estimation unit that may filter the magnitude values using a high pass filter and may generate a noise value representative of a noise portion of the received FM signal based upon the filtered magnitude values.

Abstract: A method and apparatus for enhancing signal quality within a wireless receiver are disclosed. An image of a desired signal is down-converted to a baseband signal by a digital down converter. The energy of the baseband signal is subsequently determined. If the energy of the baseband signal is equal to or greater than a predetermined threshold, then the IF is swapped for any incoming signals. If the energy of the baseband signal is less than the predetermined threshold, then the IF is maintained for any incoming signals.

Abstract: In one embodiment, the present invention includes an amplifier having a transistor stage coupled between a supply voltage and a bias current. The transistor stage has an input to receive a radio frequency (RF) input signal obtained from an antenna. The amplifier has an input impedance that is unmatched to a source impedance of the antenna. In some embodiments, this unmatched input impedance may be substantially greater than the source impedance, and may further be controlled based on a strength of the RF input signal.

Abstract: A system and method are disclosed for dynamically selecting high-side injection or low-side injection of local oscillator mixing signals based upon an assessment of signal power within the input signal spectrum that could cause unwanted images in the processed signal.

Abstract: On-chip calibration signal generation circuitry is disclosed for filter tuning for radio-frequency communications and associated methods. On-chip circuitry generates a calibration signal that is used to help set a tuning control signal that is received by a tunable front-end filter. In one embodiment, local oscillator (LO) generation circuitry is used to generate the calibration signal. In operation of this embodiment, the LO generation circuitry is tuned to the desired receive channel, or to a frequency at some offset value from the desired receive channel, and the output of the LO generation circuitry is then used as a calibration input signal for a tunable front-end filter. This calibration signal is passed through the receive path circuitry, and the resulting signal is then analyzed to help set a tuning control signal for the tunable front-end filter.
