  • Patent number: 8125249
    Abstract: A frequency measuring circuit and a semiconductor device having the frequency measuring circuit include a divided and shifted clock signal generator, a delayed clock signal generator and a phase detecting unit. The divided and shifted clock signal generator divides a frequency of a clock signal input from an exterior to output a frequency-divided clock signal, and delays the frequency-divided clock signal by a time proportional to a period of the clock signal to output a shifted clock signal. The delayed clock signal generator delays the frequency-divided clock signal by a fixed time to generate a plurality of delayed clock signals. The phase detecting unit receives the plurality of delayed clock signals and the shifted clock signal and detects a phase difference between each of the plurality of delayed clock signals and the shifted clock signal to output a plurality of phase detecting signals that represent information related to a frequency of the clock signal.
