Abstract: A method for automatic frequency tuning in a phase lock loop suitable for use in multi-band VCO wireless systems having very limited initial frequency lock times is disclosed. A predetermined subset of VCOs out of a larger bank of VCOs is selected to serve as interpolation points. The interpolation point VCOs are pre-calibrated with a predetermined voltage and the resultingly generated frequency for each of the interpolation point VCOs is stored into memory as a (frequency, VCO) pair, one pair for each interpolation point VCO. When a desired frequency then is given to the system, an appropriate VCO is selected by interpolation using the (frequency, VCO) pairs of the two most adjacent interpolation points for tracking and locking.

Abstract: A demodulation method and apparatus are provided. An RF signal is down converted to generate a first in-phase signal and a first quadrature signal of a first frequency. Limiting amplification is performed on the first in-phase signal and the first quadrature signal to generate a second in-phase signal and a second quadrature signal. The frequency of the second in-phase and quadrature signals are up converted to a third in-phase signal and a quadrature signal of a second frequency. The third in-phase and quadrature signals are up converted to generate an intermediate frequency (IF) signal of a third frequency.
