description Various embodiments provide an optical image stabilization circuit that synchronizes its gyroscope and drive circuit using gyroscope data ready signals and gyroscope reset signals. In response to a gyroscope data ready signal, the optical image stabilization circuit synchronously obtains position measurements of a camera lens when power drive signals are not transitioning from one power level to another power level, and synchronously transitions the power drive signals simultaneously with gyroscope reset signals. By synchronizing the gyroscope and the drive circuit, the gyroscope and other onboard sensing circuits are isolated from noise generated by the drive circuit.
