Abstract
The invention provides method and associated signal system improving mitigation of injection-pulling effect for an oscillator which generates an output clock under control of a control signal. The method may include: by a loop filter, filtering a deviation signal to form a filtered signal; by a SIL (self-injection locked) controller, forming an auxiliary signal which tracks the deviation signal or a phase difference between a reference clock and an output signal resulting from the output clock; and, forming the control signal by summing the filtered signal and the auxiliary signal.
