Latest Patents

David A Sealer holds a patent for a "Single electrode sense circuit for charge-coupled transversal filters." This invention involves a charge-coupled device transversal filter that features split electrodes, each with a sense portion and a complementary dummy portion. All electrode sense portions are connected to a single sense line, while the dummy portions are linked to a reference voltage. The design allows for tap weights to be determined by the relative lengths of successive sense portions, enabling weighted samples to be taken by shifting charge packets from one sense electrode position to another. This structure is less sensitive to manufacturing tolerances than earlier designs and provides a sense signal with minimal common mode component to a sense amplifier.
