Noise performance of frequency- and phase-locked CW magnetrons operated as current-controlled oscillators. [PDF]
Low-power continuous wave ``cooker'' magnetrons driven from industrial-quality switch-mode power supplies have been frequency locked by driving them as current-controlled oscillators in a phase-lock loop (PLL).

Binary phase detector gain in bang-bang phase-locked loops with DCO jitter [PDF]
Bang-bang phase-locked loops (BBPLLs) are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). In the presence of jitter, the nonlinear loop is typically analyzed by linearizing the BPD and applying linear ...

A smart DPLL for robust carrier tracking systems using uncertain rule-based IT2 fuzzy controllers
The carrier tracking synchronizes the receiver and transmitter oscillators with each other’s and is adopted as a closed-loop structure known as the phase-locked loop (PLL).
