A torque driver that includes a regulator circuit for mitigating zero-g
discontinuity effects and deadbanding is presented. An accelerometer may
comprise the torque driver and the torque driver may be arranged to
receive a control signal from a control circuit that is coupled to
deflection sensing circuitry. When the accelerometer undergoes an
acceleration the deflection sensing circuitry generates an acceleration
signal that is communicated to the control circuit. The control circuit
responsively generates a control signal, which the torque driver users to
balance a proof mass beam within the accelerometer. The regulator circuit
mitigates zero-g discontinuity effects and deadbanding by preventing the
torque signal from producing torque signals that simultaneously track the
control signal. To do this, the regulator circuit may include a
rectifying buffer and/or a modulator.
