PLL DISTURBANCE CANCELLATION |
摘要 |
<p>Techniques for cancelling a disturbance signal from a PLL output signal. In an aspect, a cancellation signal is combined with the signal input to a VCO or DCO in the PLL. In a further aspect, the appropriate cancellation signal is derived by analyzing one or more signals within the PLL. The signals within the PLL may be correlated against one or more disturbance signal templates, such as a sinusoid having a known frequency, to derive one or more correlation coefficients. The coefficients may be applied to weight one or more disturbance synthesis functions to generate the cancellation signal. Further aspects provide for joint analysis, synthesis, and cancellation of signals having unknown frequency from the PLL output.</p> |
