Title: Innovations by Yun-Xuan Zhang
Introduction
Yun-Xuan Zhang is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of wireless communication technology. With a total of 4 patents to his name, Zhang's work focuses on enhancing the efficiency and functionality of digital phase-locked loop circuits.
Latest Patents
One of his latest patents is titled "Method and apparatus for applying phase shift to digital phase-locked loop circuit to adjust frequency of local oscillator signal used by down-conversion." This invention involves a wireless communication device that includes a receiver circuit, a phase shift control circuit, and a digital phase-locked loop (DPLL) circuit. The receiver circuit applies down-conversion to an input signal according to a local oscillator (LO) signal. The phase shift control circuit generates a phase shift signal, while the DPLL circuit generates the LO signal locked to an initial frequency under a frequency-lock state. In response to the phase shift signal, the DPLL circuit adjusts the LO signal's frequency without leaving the frequency-lock state.
Another notable patent is "Method and apparatus for estimating frequency offset through accumulating complete frequency deviation values of samples obtained from sampling frequency-modulated repetition-coded segment of packet." This frequency offset estimation method involves sampling a frequency-modulated repetition-coded segment of a packet to generate multiple samples. It includes obtaining a frequency deviation value for each of the selected target samples and estimating a frequency offset value by accumulating complete frequency deviation values.
