| 摘要 |
A multi-phase clock generation circuit including a phase interpolation circuit that generates and outputs an interpolation signal based on first and second clock signals, the interpolation signal interpolating a phase between output clock signals corresponding to the first and the second clock signals, and a control circuit that generates a first control signal to adjust a phase of the interpolation signal and outputs the first control signal to the phase interpolation circuit, in which the control circuit includes a timing detection circuit that detects a timing of a change in a logic value of the interpolation signal, and a control signal generation circuit that generates the first control signal according to a detection result in the timing detection circuit.
