Abstract
A digital phase locked loop realizing high bandwidth is disclosed. The digital locked loop generates a first digital code corresponding to a difference between a rising edge of a reference signal and a rising edge of a feedback signal and a second digital code corresponding to a difference between a falling edge of the reference signal and a falling edges of the feedback signal, generates a third digital code by adding the first digital code and the second digital code, generates a first frequency control code at the rising edge of the reference signal and a second frequency control code at the falling edge of the reference signal by filtering the third digital code, outputs a specific frequency depending on the first frequency control code and the second frequency control code.
