PHYSICAL QUANTITY SENSOR
First Claim
1. A physical quantity sensor, comprising:
- a vibrating element having a drive arm section and a detection arm section;
a driving circuit generating a driving signal for driving the drive arm section with a first driving line and a second driving line; and
a detection circuit detecting a detected signal from the detection arm section with a first detection line and a second detection line, wherein at least one of the first driving line and the second driving line is wired so that a static coupling is generated with respect to the first detection line and the second detection line.

Abstract
[Problems to be Solved] To confirm whether a physical quantity sensor operates normally or not with a simple structure.
[Means to Solve the Problems] A physical quantity sensor includes a vibration element having drive arm sections and a detection arm section a driving circuit generating a driving signal for driving the drive arm sections with a first driving line and a second driving line, and a detection circuit detecting a detected signal from the detection arm section with a first detection line and a second detection line. At least one of the first driving line and the second driving line is wired so that a static coupling is generated with respect to the first detection line and the second detection line.
