<p>A delay circuit is provided to set an accurate timing among LSIs(Large-Scale Integrated circuits) with different timing settings, which operate at a high speed, by adjusting a sum delay time of a second delay device and an adjustment device. In a delay circuit, a first delay device controls a delay time according to the propagation of a signal by a delay time control signal, and a second delay device receives the delay time control signal from a frequency variable oscillator including a phase inversion device for inverting the phase of the signal. An adjustment device is connected to the second delay device in series and propagates the signal. The sum delay time of the second delay device and the adjustment device is adjusted.</p> |
