ABSTRACT:
A device for generating a geometric sequence of values of an electrical quantity (charge or voltage) with the aid of switched capacitances. A switch control means operates a plurality of switches in a predetermined time pattern so as to distribute electric charges on a plurality of capacitors. A geometric sequence of electric charges is thus stored on the capacitors in which, first-order errors caused by inaccuracies in the capacitance values of the capacitors are eliminated. Furthermore, methods are proposed to minimize the influence of inevitable stray capacitances in the arrangement.
