Abstract
A digital-to-analog converter is disclosed for converting a digital signal into its analog equivalent. The digital-to-analog converter includes a two switches capable of coupling circuit nodes to ground, a scaling capacitor having a capacitance value that equals a unit capacitance value, a first array of capacitors coupled to the first circuit node and a first switching array which couples the first array of capacitors to either ground or a reference voltage depending on the digital values of the least significant bits of the digital word being converted, a second array of capacitors coupled to the second circuit node and a second switching array which couples the second array of capacitors to either ground or the reference voltage depending on the digital values of the most significant bits of the digital word being converted.
