Phase-locked loop and method thereof and a phase-frequency detector and method thereof

A phase-locked loop, comprising:

• a charge pump configured to generate a current signal having a current level varying based on a received set of first and second output signals;
• and
• a phase-frequency detector configured to generate the first and second output signals, the first and second output signals transitioning to one of a first logic level and a second logic level based on a phase difference between a first input signal and a second input signal and at least one capacitor characteristic, the at least one capacitor characteristic compensating for at least one factor affecting operation of the charge pump.

A method of phase detection, comprising:

• generating a first output signal and a second output signal, the first and second output signals transitioning to one of a first logic level and a second logic level based on a phase difference between a first input signal and a second input signal and at least one capacitor characteristic, the at least one capacitor characteristic compensating for at least one factor affecting operation of a charge pump;
• and
• generating a current signal having a current level varying based on the first and second output signals.
