CURRENT DRIVE MODE DIGITAL-TO-ANALOG CONVERTER PREFILTER FOR REDUCED PULSE WIDTH MODULATION CONTROL DRIVE

This disclosure relates to a feedback loop circuit for an electrical signal. The feedback loop comprises a first branch having a first switch and a second switch, the first branch to receive an input signal and provide a first signal based on the input signal to a first adder and to provide a second signal based on the input signal to a second adder; and a second branch having a feedback line coupled between a third switch and the first adder, the second branch to provide an output signal based on the first signal and the second signal.
