ABSTRACT OF THE DISCLOSURE There is provided a linear current source amplifier for brushless DC motors with linear characteristic and low noise at high currents. A servo current loop for comparing a desired current with the actual winding current is provided to produce a global error signal. A plurality of linear current followers or power stages are configured such that each one of them is capable of providing a current to motor winding proportional to error signal. The power stages are arranged so that a local feedback signal proportional to the current supplied by the power stage is fed back and compared with a signal proportional to the global error signal to drive the current sources. The multiple power stage current sources in one embodiment are configured in a current loop fashion to energize the motor windings. - 24 -
