Abstract
The present invention discloses a method of building a binary weighted split capacitor array (1) for minimizing routing induced parasitic mismatch. Specifically, the binary weighted split capacitor array is built with a plurality of unit capacitors with three- dimensional structures having a top plate comprising a plurality of stacked metal plates (M2, M3, M4, M5) and a bottom plate enclosing the top plate with side walls, a floor layer and a ceiling layer to minimize top plate parasitic capacitance to the substrate, and to achieve overall equal parasitic capacitance to the substrate. (Figure 15)
