Abstract
An electronic device is provided, which includes an oscillator, a controller, and a test circuit. The oscillator generates a clock signal according to an enable signal. The oscillator determines a period of the clock signal according to an adjustment signal. The controller generates the enable signal and generates a first test signal according to the clock signal. The controller determines the period according to a first comparison signal and a second comparison signal. The test circuit, through the first test signal, tests the period to generate the first comparison signal and the second comparison signal.
