    摘要： An angular velocity detection circuit includes: a first conversion unit that includes a first operational amplifier, and converts a first detection signal, which is output from a first detection electrode and is input to a first input terminal of the first operational amplifier, into a voltage; an angular velocity signal generation unit that generates an angular velocity signal on the basis of an output signal of the first conversion unit; and a first correction signal generation unit that generates a first correction signal for reducing an offset of the angular velocity signal which occurs due to a leakage signal included in the first detection signal on the basis of a signal based on drive oscillation of the angular velocity detection element. The first correction signal is input to the first input terminal or a second input terminal of the first operational amplifier directly or through a resistor.

    摘要： A gyro sensor includes: a substrate; a first drive section; and a first detection section and a second detection section that detect angular velocity. The first detection section includes a first movable body including a first movable electrode that vibrates by vibration of the first drive section and is displaced in response to the angular velocity, and a first fixed electrode fixed to the substrate and facing the first movable electrode. The second detection section includes a second movable body including a second movable electrode that vibrates by vibration of the first drive section and is displaced in response to the angular velocity, and a second fixed electrode fixed to the substrate and facing the second movable electrode. The first movable body and the second movable body are coupled together by a first coupling section.
