Abstract
Disclosed is an angular rate detection apparatus which provides a stable output with high detection accuracy regardless of a fluctuation of a reference voltage accompanying a fluctuation of a power supply voltage. The angular rate detection apparatus includes at least a gyro sensor detection circuit connected to an oscillator, an A/D converter, a digital calculation device, and a reference voltage generation circuit. The gyro sensor detection circuit drives the oscillator, and detects an angular rate acting on the oscillator and outputs an analog detection signal. The A/D converter converts the output analog detection signal into a digital signal. The digital calculation device carries out a calculation based on the converted digital signal. The reference voltage generation circuit supplies a common reference voltage generation circuit supplies a common reference voltage to the gyro sensor detection circuit and the A/D converter.
