Latest Patents

One of Xi Yao's latest patents is for a wireless amplifier circuitry with non-linearity suppression. This electronic device includes wireless circuitry with a processor, a transceiver circuit, a front-end module, and an antenna. The front-end module features amplifier circuitry, such as a low noise amplifier, which amplifies received radio-frequency signals. The non-linearity suppression circuitry is designed to reduce non-linear behavior in components like the core amplification transistor and degeneration inductor. This innovative design includes an intermodulation distortion suppression circuit with an auxiliary amplification transistor and a frequency-selective filter.

Another notable patent is for a passive active hybrid LC filter. This invention addresses the challenges of filtering in a transceiver of an electronic device. As signal bandwidth increases, active analog filters can consume excessive power. To mitigate this issue, a passive ladder LC filter is utilized. The new structure allows for tuning components in the LC ladder filter without causing additional voltage droop, thus enhancing the overall performance of the transceiver.
