Description
Summary:A low noise interface ASIC for micro gyroscope with ball-disc rotor is realized in 0.5&#181;m CMOS technology. The interface circuit utilizes a transimpedance pre-amplifier which reduces input noise. The proposed interface achieves 0.003&#176;/s/Hz<sup>1/2</sup> noise density and 0.003&#176;/s sensitivity with &#177;100&#176;/s measure range. The functionality of the full circuit, including circuit analysis, noise analysis and measurement results, has been demonstrated.
