ABSTRACT:
A digital-to-analog converter is provided that includes an input stage and an output stage. The input stage is operable to receive a digital bit of data, to convert the digital bit into a quasi-differential current, and to convert the quasi-differential current into a first voltage using a load that is comprised of transconductance and resistance. The output stage is coupled to the input stage and is operable to generate analog data based on the first voltage.
