Abstract
Embodiments of a phase lock loop and a method for compensating a temperature thereof can output an initial tuning digital value for a voltage controlled oscillator configured to output a desired phase lock loop frequency compensated according to a temperature change. Embodiments of a phase lock loop and a method for compensating a temperature thereof can simultaneously perform a digital coarse tuning and an analog fine tuning to compensate for a temperature in a limited time.
