Abstract
A circuit device includes an amplifier circuit to which a signal from a sensor is input and a control circuit which controls the sensor and the amplifier circuit. An intermittent operation of the sensor and an intermittent operation of the amplifier circuit are controlled by an intermittent operation control signal output from the control circuit.
Claims9
A circuit device comprising:
- an amplifier circuit to which a signal from a sensor is input;
- and
- a control circuit which controls the sensor and the amplifier circuit,
- an intermittent operation of the sensor and an intermittent operation of the amplifier circuit being controlled by an intermittent operation control signal output from the control circuit, and
- the intermittent operation control signal including a first intermittent operation control signal that controls the intermittent operation of the sensor and a second intermittent operation control signal that controls the intermittent operation of the amplifier circuit, wherein
- the first intermittent operation control signal enters the active state in a predetermined period after the second intermittent operation control signal enters the active state, and
- a settling time of the sensor is shorter than a settling time of the amplifier circuit.
