Abstract
An angular velocity detection circuit includes: an angular velocity signal generation unit that generates an angular velocity signal on the basis of an output signal of a differential amplifier unit that differentially amplifies a signal based on an output signal of a first conversion unit and a signal based on an output signal of a second conversion unit; and a correction signal generation unit that generates a correction signal for reducing an offset of the angular velocity signal which occurs due to leakage signals which are respectively included in the first detection signal and the second detection signal on the basis of a signal based on drive oscillation of the angular velocity detection element. The correction signal is input to a circuit that is located on a first signal path ranging from the first detection electrode of an angular velocity detection element to the differential amplifier unit.
