Abstract
A method of applying digital pre-distortion includes: outputting, by a look-up table, a first table value based on an input digital signal; adding the first table value and the input digital signal to generate a first combined signal comprising a first combined value having a first integer coefficient and a first fractional coefficient; separating the first integer coefficient from the first fractional coefficient to generate a first integer signal representing the first integer coefficient and a first fractional signal representing the first fractional coefficient; generating a delta-sigma modulated signal based on the first fractional signal; converting, by a first digital-to-analog, a first digital signal into a first analog signal, wherein the first digital signal is representative of the first integer signal; and converting, by a second DAC, a second digital signal into a second analog signal, wherein the second digital signal is representative of the delta-sigma modulated signal.
