<p>PHN 9866 27-1-1981 "An arrangement for generating a sequence of binaryweighted values of an electrical quantity". The device in accordance with the invention is capable of generating a sequence of values of an electrical quantity (charge or voltage) with the aid of switched capacitances, which values are proportioned as the terms of a geometric sequence. Owing to the switching methods used, first-order errors caused by inaccuracies in the capacitance values of the capacitors are fully eliminated. Furthermore, methods are proposed in order to minimize the influence of inevitable stray capacitances in the arrangement.</p> |
