Latest Patents

Yeo's latest patents include a "Method and device for radio frequency voltage limiting." This invention provides a method and device for radio frequency (RF) limiting, which comprises an analog limiter that limits the voltage of an RF input to a predetermined safe range during power-off or power-up until a disable control signal is received from the digital controller. Additionally, it features a sensing circuit that determines the value of each bit of a preset current sensing code and senses the limiting voltage. The digital controller manages the RF limiting function based on the preset current sensing code and ensures that the analog limiter stops limiting the voltage if it is within an acceptable range.

Another significant patent is the "Active load modulation technique in near field communication." This invention involves a near field communication (NFC) device designed to prepare a carrier signal for active load modulation, supporting both synchronous and asynchronous transmissions. The NFC device includes a local clock generator, a clock extractor, a frequency tracking module, and a phase tracking module, all working together to ensure precise communication.
