According to the present invention, a phase locked loop device comprises receives a first signal from a loop filter through a first input terminal to convert the first signal to have the value of a first slope and receives a second signal from the loop filter through a second input terminal to convert the second signal to have the value of a second slope so as to control a slope ratio of the values of the first and second slopes, thereby reducing capacitance of the loop filter by using two gain values to be easily integrated in one chip. |
