Latest Patents

Xu Shao holds a patent for "Transmit wake-up architectures in RF front-ends." This invention features a transmit wake-up front-end architecture embedded in a single chip for wireless systems. The architecture includes an RF front end with an antenna port and a transmit-receive port. It comprises three alternate paths enabled by two switch blocks, namely the input switch block and output switch block. A coupling resistor is connected from the directional coupler port to ground, while an isolated resistor is connected from the directional coupler isolation port to ground. An envelope detector utilizes a high-frequency RF signal from a transceiver as input and provides an envelope of the original RF signal as output, which is connected to an envelope amplifier. Additionally, a threshold detector is implemented in the RF front-end wake-up circuit connected to the envelope amplifier. A logic control block is also integrated, which interacts with the threshold circuitry to switch operational modes in the RF front end. Xu Shao's innovative approach has led to the development of a highly efficient architecture that is crucial for modern wireless communication.
