ABSTRACT:
An angular rate sensor comprises a pair of driven tines and a pair of output tines connected to the driven tines by a stem portion. A detection circuit including a set of output electrodes, associated with each output tines, generates a detection signal related to angular rate. A feedback circuit, including a further set of electrodes associated with each driven tine; utilizes a phase quadrature component of the detection signal so as to drive the driven tines towards a condition of torsional balance.
