Abstract
The device for jitter measurement and a method thereof are provided. The device for jitter measure includes a signal retrieving module, a signal amplifying module, an edge detecting module, and a time-to-digital converting module. The signal retrieving module receives a signal-under-test, and retrieves a first pulse signal having a pulse width equal to a period of the signal-under-test. The signal amplifying module amplifies the pulse width of the first pulse signal and thereby generates a second pulse signal. The edge detecting module detects a rising edge and a falling edge of the second pulse signal, and generates a first indication signal and a second indication signal according to the respective detected results. The time-to-digital converting module converts the pulse width of the second pulse signal existed in time domain to a digital signal according to the first indication signal and the second indication signal.
