Abstract:
A switched capacitor digital/analog converter comprising an input for an n bit digital word, where n is an integer greater than two, and n capacitors having values C0, . . . , Cnâˆ’1 such that Cxx+1 for each integer x greater than âˆ’1 and less than (nâˆ’1) and such that Cy+1 is different from 2Â·Cy for at least one integer y greater than âˆ’1 and less than (nâˆ’1), said capacitors having first electrodes which are connected together, each of said capacitors having a second electrode which is connectable to one of first and second reference voltages in accordance with a value of a respective bit of said n bit word.
