Latest Patents
One of Graham's latest patents is an "Analog audio signal enhancement system using a noise suppression algorithm." This invention provides systems and methods for removing noise from an input analog signal in continuous time. The architecture includes an analog filtering system with VLSI circuitry that separates an analog input signal into multiple sub-band signals. An analog gain system, also utilizing VLSI circuitry, calculates a gain for each sub-band signal to suppress noise effectively. In preferred embodiments, the VLSI circuitry incorporates floating gate technology.
Another notable patent is for "Systems and methods for programming floating-gate transistors." This invention features a floating-gate transistor array and a method for programming it. The array consists of multiple transistors arranged in rows and columns, with each row and column having programming switches connected to the floating-gates and drains, respectively. This setup allows for the selection and programming of desired floating-gate transistors, enabling run-time programming through an indirect method where two transistors share a floating gate.
