Abstract: A actuator driver includes a digital filter configured to perform phase compensation of a digital torque command signal using a fed-back digital signal; a digital PWM generator configured to generate a plurality of pulse-width modulated PWM control signals in response to an output of the digital filter; at least one H bridge configured to select and output a first or second terminal voltage in response to the plurality of PWM control signals; first and second continuous time ΔΣ A/D converters configured to convert the first and second terminal voltages from analog to digital, respectively; and a feed-back filter configured to decimate outputs of the first and second continuous time ΔΣ A/D converters to feed back the digital signal to the digital filter.
