AC and DC voltage standards based on silicon micromechanics

Micromechanical AC and DC standards, suitable for compact, low-cost precision electronics applications are described. The standards are based on controlling the charge of a parallel-moving-plate capacitor. We expect that the voltage standards based on mechanical and geometrical properties of single crystalline silicon can have a high stability. We show the basic principle of the AC and DC standards and preliminary experiments with the AC voltage standard.
