Abstract
An object of the present invention is to reduce a rise time required for stabilizing the vibration state of a vibrator and the scale of a circuit needed for the activation of a driving vibration in exciting the driving vibration in the vibrator. A driving vibration is excited in a vibratorfor outputting a detection signal generated based on the driving vibration and a physical value, and the physical value is measured based on the detection signal. The driving vibration is excited using a circuitA for self-excited vibration having a CR oscillatorA to generate an oscillation loop together with the vibratorAn activating signal of rectangular wave is applied on the vibratorusing the CR oscillatorA to start the driving vibration in the vibrator
