Introduction

Shaobo Liu is a prominent inventor based in Sunnyvale, California. He has made significant contributions to the field of electronics, particularly in the design of circuits for phase-locked loops. With a total of seven patents to his name, Liu's work has had a considerable impact on the industry.

Latest Patents

One of Liu's latest patents is titled "Reference clock switching in phase-locked loop circuits." This invention involves a clock generator circuit that includes a multiplex circuit and a phase-locked loop circuit. The multiplex circuit generates a reference clock signal by selecting from different clock signals. When the reference clock signal switches from one clock signal to another, the phase-locked loop circuit disables phase-locking and enters a frequency acquisition mode. During this mode, the output clock signal's frequency is adjusted based on the newly selected reference clock signal. After a designated time, the phase-locked loop circuit resumes its phase-locking operation.

Another notable patent is "Hybrid asynchronous gray counter with non-gray zone detector for high performance phase-locked loops." This invention describes systems, apparatuses, and methods for implementing a hybrid asynchronous gray counter with a non-gray zone detector. The circuit includes an asynchronous gray counter coupled to control logic, which programs the counter to operate in various modes. In one mode, it serves as a frequency detector, while in another, it acts as a coarse phase detector. Additionally, it functions as a multi-modulus divider to create a feedback clock. This innovative approach reduces power consumption and area utilization by using a single asynchronous gray counter for multiple functions.
