    摘要: A force compensated comb drive for a microelectromechanical system includes a MEMS mechanism for providing an output signal representative of a physical quantity; a comb drive for actuating the MEMS mechanism; a comb drive circuit for providing a drive signal to the comb drive for developing a predetermined displacement applied by the comb drive to the MEMS mechanism; an automatic gain control responsive to a change in the force to provide a correction signal to the comb drive circuit to maintain the predetermined motion; and a compensation device responsive to the correction signal for adjusting the output signal of the MEMS mechanism to compensate for errors in the output signal due to a change in the predetermined force.

    摘要: A microelectromechanical vibration isolation system includes a microelectromechanical structure having a plurality of fin apertures etched therethrough, and a plurality of fins each disposed within a respective one of the plurality of fin apertures and spaced apart from the microelectromechanical structure so as to define a fluid gap therebetween. The fluid gap is configured to provide squeeze film damping of vibrations imparted upon the microelectromechanical structure in at least two dimensions. The system further includes a frame surrounding the microelectromechanical structure, and a plurality of springs each coupled to the microelectromechanical structure and to the frame. The plurality of springs is configured to support the micromechanical structure in relation to the frame.
