Abstract
An optimum assignment is found for the distribution of area in surface micromachined lateral capacitive accelerometers between stationary and moving electrodes to improve the S/N ratio of the sensor. Depending on etching hole geometry, the sensitivity can increase by a factor of up to 1.76
