摘要: An apparatus (100, 200) and method (300) for sensing acceleration are provided. The includes producing (305) a first signal in response to an sensed by transducer, (310) second based on the signal, actuating (315) transducer remove offset transducer. represents acceleration, low frequency component associated with (100) (102) capacitance system (104, 106, 108) from representing compensation (112, 110) coupled between produces substantially removing of
