Abstract
Systems and methods are provided for compensating errors. A system includes a microelectromechanical systems (MEMS) oscillating structure configured to oscillate about a rotation axis; a phase error detector configured to generate a phase error signal based on measured event times and expected event times of the MEMS oscillating structure oscillating about the rotation axis; and a compensation circuit configured to receive the phase error signal, remove periodic jitter components in the phase error signal to generate a compensated phase error signal, and output the compensated phase error signal.
