A method for providing acceleration data with reduced substrate-displacement bias includes receiving in an accelerometer an external acceleration, determining the acceleration data with reduced substrate displacement bias in a compensation portion in response to a first and a second displacement indicators from a MEMS transducer, and, in response to substrate compensation factors from a MEMS compensation portion, outputting the acceleration data with reduced substrate displacement bias, wherein the first displacement indicator and the second displacement indicator are determined by the MEMS transducer relative to a substrate in response to the external acceleration and to a substrate displacement, and wherein the substrate compensation factors are determined by the MEMS compensation portion relative to the substrate in response to the substrate displacement.
