CAPACITOR STRUCTURE WITH CORRELATED ERROR MITIGATION AND IMPROVED SYSTEMATIC MISMATCH IN TECHNOLOGIES WITH MULTIPLE PATTERNING

Abstract:

Capacitor arrays and methods of operating a digital to analog converter are described. In an embodiment, a capacitor array includes a unit capacitor (Cu) structure characterized by a unit capacitance value, a plurality of different super-unit capacitor structures, and a plurality of different sub-unit capacitor structures, each different sub-unit capacitor structure having a different capacitance defined by a division of the unit capacitance value.
