Frequency Lock Stability in Device Using Overlapping VCO Bands |
摘要 |
A system and method are provided for frequency lock stability in a receiver using overlapping voltage controlled oscillator (VCO) bands. An input communication signal is accepted and an initial VCO is selected. Using a phase-locked loop (PLL) and the initial VCO, the frequency of the input communication signal is acquired and the acquired signal tuning voltage of the initial VCO is measured. Then, the initial VCO is disengaged and a plurality of adjacent band VCOs is sequentially engaged. The acquired signal tuning voltage of each VCO is measured and a final VCO is selected that is able to generate the input communication signal frequency using an acquired signal tuning voltage closest to a midpoint of a predetermined tuning voltage range.
