A switched capacitor digital/analog converter is provided for performing non-linear conversion. An input receives an n bit digital word for conversion. The individual bits of the input word control electronic switches which switch the plates of n capacitors between upper and lower reference voltages. The capacitors have values C0, . . . Cn-1 such that Cx<Cx+1 for each integer x greater than -1 and less than (n-1) and such that Cy+1 is different from 2.Cy for at least one integer y greater than -1 and less than (n-1). The other electrodes of the capacitors are connected together and to the output of the converter. |
