Crystal oscillator noise compensation method for a multi-loop PLL

A multi-loop phase locked loop (PLL) system with noise attenuation has a first PLL including a local oscillator, a second PLL coupled to an output of the first PLL, and a third PLL in a feedback path between the second PLL and first PLL. A first phase comparator compares an input signal with the fir...
