I performed a temperature cycle check on the ASM330LHB chip. Relative to the warming process (red curve), during the cooling process (blue curve), it is prone to large zero-bias jumps (in the red box of the picture)。
The jump during the cooling process, I feel like there is a correction mechanism in the gyro in the chip, which recognizes a large shift in the gyro zero bias during the cooling process, and then immediately corrects the large zero bias shift.
Can you please help explain what causes this?
Note: These data on the image have been smoothed for 10 seconds.
