Physical quantity detection circuit for allowing precise adjustment of the phase relationship between a sensor signal and a detection signal |
摘要 |
A PLL circuit generates a plurality of oscillated clocks having different phases. A selector selects one of the plurality of oscillated clocks generated by the PLL circuit. A detection circuit detects a physical quantity signal corresponding to the physical quantity given to a physical quantity sensor from a sensor signal received from the physical quantity sensor based on the oscillated clock selected by the selector.
