A reduced hardware control circuit device includes a current loop for broad band Hard Disk Drive applications. The current loop detects the value of the current flowing on the coils of a voice coil electric motor incorporated in the Hard Disk Drive. A sensing resistance is connected in series with the motor and at least a driving driver for a relative motor coil. Advantageously the current loop is a transconductance loop with a first transconductance amplifier associated with the sensing resistance. A second transconductance amplifier is provided for fixing the current value to be applied to the motor. The circuit device advantageously is deprived of a local compensation in correspondence with the first transconductance amplifier.
