ABSTRACT:
An N bit converter, where N is an integer, is provided for effecting A/D and D/A conversions by utilizing a capacitor array and a resistor voltage divider string. The converter may be linear or nonlinear and the structure remains monotonic independent of the accuracy of the converter. Although monotonic, device count is minimized and only 2.sup.(N/2) stages are required to implement an N bit linear converter. Reduction of the number of circuit elements is achieved, in part, by shared use of decode circuitry for the most significant and least significant bits of the N bits.
