Nonlinear observer for Frequency Meter in Digital Phase Locked Loops
This paper presents an efficient and easy to implement observer to increase the output frequency measurement accuracy on a Digital Phase Locked Loop feedback path. The proposed observer improves the Radio Frequency PLL output phase noise and cancels the measurement offset. Theoretical expressions have been derived to evaluate its efficiency and simulation results illustrate the phase noise reduction.
