Abstract
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 C , . . . C such that C <C for each integer x greater than −1 and less than (n−1) and such that C is different from 2·C 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.
