Charge-coupled-device quantizing circuit

Abstract From the Canadian patent

A device for quantizing analog signals employing chargecoupled-device technology including a p-type substrate such as silicon having a dielectric insulating layer thereon which may be silicon dioxide. A plurality of gates or electrodes are embedded in the insulating layer and are arranged in linear relationship to alternately form potential wells in the substrate and to function as transfer gates between the wells. An analog signal represented by a quantity of charge carriers is injected into substrate and is transferred through the substrate to sequentially fill the potential wells until the original quantity of charge carriers is exhausted. The potential wells can be equal in size so that …
