With a total of 2 patents to his name, his work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of his latest patents is titled "Nested cascaded mixed-radix digital delta-sigma modulator." This invention describes a nested mixed-radix DDSM that guarantees zero systematic frequency error when used as a divider controller in a fractional-N frequency synthesizer. The architecture allows for the use of higher-order auxiliary modulators and shaped dither signals to eliminate feedthrough spurs completely. By increasing the number of levels in the cascade, the moduli of the individual modulator stages can be reduced, thereby increasing the speed of the synthesizer.
Another notable patent is "Apparatus for reducing wandering spurs in a fractional-N frequency synthesizer." This invention provides a fractional-N frequency synthesizer that includes a divider controller comprising a multistage noise shaping (MASH) digital delta-sigma modulator with L stages. The Lth stage is configured to receive a high amplitude dither signal as input, enhancing the performance of the synthesizer.
