Abstract
An accelerometer is provided having a power circuit, a detection circuit, and a compensation circuit. The compensation circuit is operative to measure an offset voltage occurring between an output reference voltage from the power circuit and an output voltage from the detection circuit state, store the offset voltage during a zero acceleration, and output the stored offset voltage to alter the output voltage of the detection circuit.
