ABSTRACT:
An apparatus and method for a micro-machined device having a movable mass rotatably suspended from a frame by one or more hinges for rotation relative thereto frame. A DETF resonator is suspended between the frame and reaction mass, and a capacitor is provided between the frame and movable mass for transmitting a drive signal to the DETF resonator.
