A performance orientated closed-loop digital amplifier architecture which solves the traditional problems facing digital-input open-loop amplifiers, and is shown to have performance advantages over equivalent systems implemented using conventional analog amplifier technology. Through the use of a high-resolution data-path and the global feedback structure, significant improvements in retained resolution at the amplifier output are evident.
