摘要： A method for processing a plurality of signals may include amplifying an input signal and generating a wideband signal from the amplified input signal. The method may further include bandpass filtering the generated wideband signal to generate a narrowband signal, and adjusting amplification of the input signal based on a narrowband received signal strength indication of the generated narrowband signal, and/or a wideband received signal strength indication of the generated wideband signal. The amplified input signal may be downconverted to generate the wideband signal. The amplified input signal may be downconverted to an intermediate frequency (IF) and/or to a baseband signal to generate the wideband signal. At least one blocker signal may be bandpass filtered from the amplified input signal.

摘要： Methods and systems for processing a plurality of signals are disclosed herein. Aspects of the method may comprise amplifying an input signal. The amplified input signal may be bandpass filtered. Amplification of the input signal may be adjusted based on only narrowband received signal strength indication of the bandpass filtered amplified input signal.

Signal strength of a desired signal from the amplified input signal may be measured. The amplification of the input signal may be adjusted utilizing a triple well (TW) NMOS transistor. A control signal may be generated based on the narrowband received signal strength indication of the bandpass filtered amplified input signal. The amplification of the input signal may be adjusted based on at least one of the generated control signals.

摘要： Aspects of compensating for DC offset in an RF receiver may comprise sampling data from at least one of a plurality of output paths, selecting a sampled data and generating at least one feedback signal based on the selected sampled data. The generated feedback signal may be fed back to at least one of a plurality of input paths, and at least one of the feedback signals may be of an opposite polarity to the selected sampled data. The selected sampled data may be converted to a digital sample, a plurality of the digital samples accumulated, and an average of the plurality of the digital samples calculated. A digital feedback value may be generated based on the average. A phase of the digital feedback value may be adjusted via a derotator, which may utilize the coordinate rotation digital computer (CORDIC) algorithm.

摘要： A method and system sharing a Bluetooth processor for FM functions are provided. The single chip may comprise an integrated Bluetooth radio, an integrated FM radio, and processor system. A processor in the processor system may be utilized for Bluetooth and FM data processing and may time multiplex between the Bluetooth and FM data processing based on interrupt signals. The processor may operate in a low power mode based on a clock signal generated from a low power oscillator. When a Bluetooth interrupt signal is received, the processor may enable Bluetooth data processing that may be based on a Bluetooth clock signal. When an FM interrupt signal is received, the processor may enable FM data processing that may be based on an FM clock signal. When data processing is complete, the processor may return to the low power mode operation.
