| 摘要 | A detection device includes a driving circuit that drives a vibrator, and a detection circuit that receives a detection signal from the vibrator and performs a detection process of detecting a physical quantity signal corresponding to a physical quantity from the detection signal. The driving circuit performs intermittent driving in which the vibrator is driven in a driving period, and is not driven in a non-driving period, and the detection circuit performs the detection process of the physical quantity signal in the non-driving period of the intermittent driving. | ||

| 主权项 | 1. A detection device comprising: a driving circuit that drives a vibrator; and a detection circuit that receives a detection signal from the vibrator and performs a detection process of detecting a physical quantity signal corresponding to a physical quantity from the detection signal, wherein the driving circuit performs intermittent driving in which the vibrator is driven in a driving period, and is not driven in a non-driving period, wherein the detection circuit performs the detection process of the physical quantity signal in the non-driving period of the intermittent driving, and wherein the driving circuit performs the intermittent driving in which the driving period and the non-driving period of the vibrator are alternately repeated. | ||
