Patent ID: 8659459

Claim:
A split-capacitor digital-to-analog converter comprising: a first capacitor bank including a plurality of capacitors, each of the plurality of capacitors of the first capacitor bank having a capacitance that is a product of an integer and a unit capacitance, each of the plurality of capacitors of the first capacitor bank being connected to a first common node; a second capacitor bank including a plurality of capacitors, each of the plurality of capacitors of the second capacitor bank having a capacitance that is a product of an integer and the unit capacitance, each of the plurality of capacitors of the second capacitor bank being connected to a second common node; a first split capacitor connected to the first common node and to the second common node; a first dummy capacitor connected to the first common node; and a second dummy capacitor connected to the second common node, wherein each of the first split capacitor and the first dummy capacitor has a capacitance that is a product of an integer and the unit capacitance.
