Abstract :
This paper introduces an algorithm called 3-stage current sorting (3S-CS) in half-unary weighted current cells to improve the linearity of a current-steering digital-to-analog converter (DAC). Based our statistical analysis and simulation results, the proposed algorithm improves the DAC static linearity as well as its dynamic performance.
