摘要： Phase profile generator systems and methods are disclosed. A system includes a signal generator, a target phase trajectory module, an error detector and a control loop filter. The signal generator is configured to generate an output signal. In addition, the target phase trajectory module is configured to track a target phase trajectory and determine a next adjustment of the output signal to conform the output signal to a portion of the target phase trajectory. Further, the error detector is configured to determine an error between the output signal and a current target phase trajectory value that precedes the portion of the target phase trajectory, where the determination of the error is independent of the next adjustment of the output signal. Moreover, the control loop filter is configured to control the signal generator in accordance with both the next adjustment and the error to generate a phase profile.

摘要： There is provided a method for reducing lock time in a phase locked loop. The method includes detecting a saturation condition on a path within the phase locked loop. The method further includes temporarily applying saturation compensation along the path when the saturation condition is detected.

摘要： There is provided a tank based oscillator. The oscillator includes one or more active devices, one or more passive devices, and a tank circuit decoupled from the active devices using at least one of the one or more passive devices. A coupling ratio between the tank circuit and the one or more active devices is set such that a maximum value of an oscillation amplitude of the tank circuit is limited based upon a breakdown of only the one or more passive devices.
