摘要：A capacitive digital to analog converter (DAC) includes a first switching devicethat receives first, second, third, and fourth reference potentials at respective inputs andthat selectively connects one of the first, second, third, and fourth reference potentials

to a first output. The first and second reference potentials are approximately equal. Thethird and fourth reference potentials are approximately equal. A first capacitor isconnected between the first output and a common node. A second switching devicereceives the first, second, third, and fourth reference potentials at respective inputs andselectively connects one of the first, second, third, and fourth reference potentials to asecond output. A second capacitor is connected between the second output and thecommon node.
