Phase profile generator

A phase profile generator device, comprising:

• a signal generator configured to generate an output signal;
• a monitoring unit configured to monitor a current state of the output signal;
• a target phase trajectory module configured to track a target phase trajectory and determine an adjustment of the output signal independently of the monitored current state to conform the output signal to the target phase trajectory;
• and
• a control loop filter that is configured to directly receive the adjustment to control the signal generator in accordance with the adjustment and generate a phase profile.

A phase profile generator apparatus comprising:

• a signal generator configured to generate an output signal;
• a target phase trajectory module configured to track a target phase trajectory and determine a next adjustment of the output signal to conform the output signal to the target phase trajectory, wherein the target phase trajectory module further includes a linearization module configured to implement a modification of the next adjustment to linearize the output signal;
• an error detector configured to determine an error between the output signal and the target phase trajectory;
• and
• a control loop filter that is configured to receive the error separately from the next adjustment and is configured to control the signal generator in accordance with both the next adjustment and the error to generate a phase profile.

A method for generating a phase profile comprising:

• tracking a target phase trajectory to determine a next adjustment of an output signal of a signal generator based on a portion of the target phase trajectory to conform the output signal to the portion of the target phase trajectory;
• determining an error between the output signal and a current target phase trajectory value that precedes the portion of the target phase trajectory, wherein the determination of the error is independent of the next adjustment of the output signal;
• and
• controlling the signal generator in accordance with both the next adjustment and the error simultaneously to generate the phase profile.
