Latest Patents

One of his latest patents is a reference voltage circuit. This invention features a single electrode sense circuit designed for charge-coupled transversal filters. The charge-coupled device transversal filter incorporates split electrodes, each having a sense portion and a complementary dummy portion. All electrode sense portions are connected to a single sense line, while all dummy portions are linked to a reference voltage. The tap weights are determined by the relative lengths of successive sense portions, and weighted samples are obtained by shifting charge packets from one sense electrode position to another. This design is less sensitive to manufacturing tolerances than earlier structures and provides a sense signal with essentially no common mode component to a sense amplifier.
