  • Abstract
    The relationship between yield, area, and impedance distribution in dual-string DACs is developed. Optimal area allocation and impedance distributions strategies for maximizing yield in the presence of local random process variations are introduced. Simulation results show that a factor of 4 or more reduction in area for a given yield is possible if typical area/impedance allocations are replaced with an optimal area/impedance allocation.
