Abstract
A capacitor array circuit having at least two capacitors, switching circuitry coupled to the capacitors and to input, output and common nodes and control circuitry. The control circuitry operates to sequentially switch the array through three different states so that a voltage is developed across each of the capacitors which is at a fixed value proportional to a voltage present at the input node. The fixed and thus determinate voltage drop across each of the capacitors operates to define voltages at any nodes intermediate the capacitors thereby, among other things, insuring reliable operation of the capacitor array circuit.
