Abstract
A digital-to-analog converter is provided for accomplishing analog output characteristics using different digital-to-analog conversion type digital signal processing schemes. A plurality of bits of a received digital signal are divided into a plurality of bit groups. A digital signal processing unit includes a plurality of bit group digital signal processors for receiving the plurality of bit groups. The plurality of digital signal processors employ one or more digital-to-analog conversion type digital signal processing schemes for generating a plurality of digital signal processed outputs. The converter adds the plurality of digital signal processed outputs to generate a composite signal processed output, and includes a weight generating unit for controlling a plurality of shared weight generating elements in response to the composite digital signal processed output to generate an analog output signal.
