Linearization of Multilevel, Multiwidth Digital PWM with Applications in Digital-to-Analog Conversion

The process of uniformly sampled pulse-width modulation is investigated as a means of high-performance digital-to-analog conversion where comparisons of duality are made with signals in standard modulated format. Emphasis is placed on using linearization algorithms to suppress nonlinear distortion products, and a new digital-to-analog conversion architecture is proposed that employs digital linearization together with a multiwidth and multiamplitude signal format configured within a current-steering autocalibration system topology.
