Abstract: A pulse width estimation method, applied between an integrated circuit and a circuit system for generating a reference pulse with a predetermined pulse width, includes steps for the following: generating an under-test pulse with an under-test pulse width by the integrated circuit; delivering the under-test and reference pulses to the integrated circuit for multiplying the under-test pulse width and the predetermined pulse width thereof by a timing gain and thereby obtaining a gained under-test pulse and a gained reference pulse, respectively; providing, by the integrated circuit, a count pulse for sampling the gained under-test pulse and the gained reference pulse and thereby obtaining a first count number and a second count number, respectively; and estimating the under-test pulse width by using the predetermined pulse width, the first count number and the second count number. A pulse width estimation device is also provided.
