摘要
A loop filter, a phase locked loop, and a method of operating a loop filter for randomly determining the amplitude of a control voltage are disclosed. The loop filter according to the present invention includes a timing adjustment clock generator and a variable capacitor unit. The timing adjustment clock generator generates a timing adjustment clock that is randomly determined whether the first logic state appears. The variable capacitor unit is charged by the input current, and the capacitance changes according to the logic state of the timing adjustment clock.
