Latest Patents

One of Liu's latest patents focuses on detecting time delay between circuits to achieve time synchronization. This patent provides systems, circuits, and methods for synchronizing devices in the time-domain. The method includes determining a round-trip number based on the width of one cycle of a timestamping clock signal. This round-trip number represents the times a clock signal is transmitted in a loop from a timing-leader component to a timing-follower component and back. The method also utilizes the timestamping clock signal to detect a cumulative time delay, enabling synchronization of the timing-follower component with the timing-leader component.

Another significant patent by Liu is related to phase clock performance improvement for systems embedded with Global Navigation Satellite System (GNSS) receivers. This patent outlines systems and methods for storing phase history and enhancing phase accuracy for embedded GNSS receivers. It includes storing a phase history of the GNSS receiver output and determining an expected value of phase based on this history. In cases of degradation of the GNSS receiver output, the method adjusts the output using the expected value of phase, ensuring performance enhancement.
