摘要
A monolithic surface micromachined Z-axis vibratory rate gyroscope with an on-chip A/D converter is fabricated in a monolithic MEMS/circuits technology with 2 mu m CMOS and 2.25 mu m-thick mechanical polysilicon. The on-chip position sense circuit uses correlated double sampling to reject 1/f and kT/C noise and resolves 0.02Angstrom displacements. The gyroscope achieves a noise floor of 3 degrees/sec/root Hz at atmospheric pressure and operates from a single 5V supply.
