Analysis on the Detection Capacitance of Comb Micro-Machined Gyroscope

Abstract:

Article Preview

The micro-machined gyroscope is a kind of typical micro-electro-mechanical sensor, its typical working mode is electrostatic drive and comb capacitive detection. As for as the transverse detection capacitance structure now commonly used, we find out that the relationship between capacitance variation and displacement is nonlinear through analyzing its detection capacitance. This nonlinearity will greatly affect the dynamic performance of micro-machined gyroscope.
