Adjustable voice coil motor driver
A method of configuring a signal for controlling a voice coil motor (VCM) is disclosed. A voltage at an error amplifier of a VCM driver is accessed. A target value at the error amplifier is accessed. A difference value between the target value and the voltage is determined. An impedance value of the...

| Zusammenfassung: | A method of configuring a signal for controlling a voice coil motor (VCM) is disclosed. A voltage at an error amplifier of a VCM driver is accessed. A target value at the error amplifier is accessed. A difference value between the target value and the voltage is determined. An impedance value of the variable compensation coupled with the error amplifier is adjusted, based on the difference value. |
