METHOD AND SYSTEM FOR FILTER CALIBRATION USING FRACTIONAL-N FREQUENCY SYNTHESIZED SIGNALS
A method and system for filter calibration using fractional-N frequency synthesized signals are presented. Aspects of the method may include generating an LO signal by a PLL circuit within a chip. A reference signal may be generated based on the generated LO signal and a synthesizer control signal....

| description | A method and system for filter calibration using fractional-N frequency synthesized signals are presented. Aspects of the method may include generating an LO signal by a PLL circuit within a chip. A reference signal may be generated based on the generated LO signal and a synthesizer control signal. A frequency response for a filter circuit integrated within the chip may be calibrated by adjusting parameters associated with the filter circuit based on the generated LO signal. Aspects of the system may include a single-chip multi-band RF receiver that enables generation of a LO signal by a PLL circuit within the single-chip, and enables calibration of a frequency response for a filter circuit integrated within the chip. A reference signal may be generated based on the generated LO signal and a synthesizer control signal. The frequency response may be calibrated by adjusting the filter based on the generated reference signal. |
