Semiconductor integrated circuit, and sensor system and vehicle including the same

A semiconductor integrated circuit constituting a part of a sensor signal processing apparatus for processing a sensor signal output from a sensor, the circuit comprising:

• a first terminal to which one end of a vibrator externally attached to the semiconductor integrated circuit is connected;
• a second terminal to which the other end of the vibrator is connected;
• and
• an oscillation circuit configured to oscillate the vibrator connected via the first terminal and the second terminal,
• wherein the oscillator circuit is configured to intermittently oscillate the vibrator based on a control signal,
• wherein a first period during which the oscillation circuit oscillates the vibrator and a second period during which the oscillation circuit does not oscillate the vibrator are alternately switched,
• wherein, during the first period, potentials of the first terminal and the second terminal are alternately switched complementarily to a high level and a low level, and
• wherein, during the second period, the potentials of the first terminal and the second terminal are fixed to the low level.
