Latest Patents
One of his latest patents is titled "Circuits, chips, systems and methods for eliminating random perturbation." This invention provides a circuit, chip, system, and method designed to eliminate random perturbation. The circuit includes a weight calculating module that receives digital signals and random perturbation digital quantities. It uses a least mean square error algorithm to calculate weight deviation iteration coefficients based on these inputs, allowing for real-time updates of perturbation weight. This innovation ensures that even with changes in the manufacturing process or working environment, the perturbation weight can be dynamically adjusted to effectively eliminate perturbation signals in digital signals.
Another notable patent is the "Clock drive circuit." This invention comprises an input stage, a double-ended to single-ended conversion stage, and a driver output stage connected in sequence. The input stage features two mutually loaded differential amplifiers and a common mode negative feedback loop. The differential amplifiers amplify a differential clock signal to generate a common mode voltage, which is stabilized by the common mode feedback circuit. The double-ended to single-ended conversion stage transforms a differential sine clock signal into a single-ended square wave clock signal, while the driver output stage enhances the drive capability of the square wave clock signal.
