Abstract
A clock generator including a phase frequency detector configured to compare a phase and a frequency of a reference clock signal with a phase and a frequency of a first output clock signal and generate a detection signal based on a difference in the phases and frequencies of the clock signals; a loop filter configured to generate a first control voltage signal based on the detection signal; a first voltage controlled oscillator configured to generate and output a first output clock signal based on the first control voltage signal, a modulation filter configured to generate a modulation voltage signal based on the reference clock signal and generate a second control voltage signal by combining the modulation voltage signal and the first control voltage signal, and a second voltage controlled oscillator configured to generate and output a second output clock signal based on the second control voltage signal is provided.
