Systems and methods for frequency domain calibration and characterization

A system for assigning a characterization and calibrating components in a phase locked loop, the system comprising:

• a loop gain component configured to generate a first signal having a loop gain based on a gain calibration signal;
• a digital controlled oscillator configured to generate an oscillatory signal from the first signal based on a oscillator calibration signal;
• a time to digital converter configured to generate a time output signal from the oscillatory signal using a delay amount, wherein the delay amount is set according to a delay calibration signal;
• and
• a characterization and calibration component configured to generate the gain calibration signal, the oscillator calibration signal, and the delay calibration signal according to the oscillatory signal and the time output signal.

A method for assigning a characterization and calibrating a component, the method comprising:

• obtaining frequency measurements of an oscillatory signal;
• assigning a characterization to a component parameter based on the obtained frequency measurements;
• and
• generating a calibration signal based on the characterized component parameter.
