Abstract
A micro-gyroscope having electronic alignment by performing an electronic coordinate transformation on control voltages (VTX, VTy) through an attenuator network thereby canceling first and second harmonic signals from the output (Vthx, Vthy). The micro-gyroscope is tuned by automatic electronic compensation based on quadrature error that is applied to correct for variations in the gyroscope.
