Title: Innovations of Junqi Hua in Circuitry and Integrated Circuits
Introduction
Junqi Hua is a notable inventor based in Portland, Oregon, who has made significant contributions to the field of circuitry and integrated circuits. With a total of five patents to his name, he has developed innovative solutions that enhance the functionality and testing of serial interfaces.
Latest Patents
One of Junqi Hua's latest patents is titled "Circuitry to facilitate testing of serial interfaces." This invention describes a system that aids in testing the clock and data recovery functionality of a receiver. The serial interface includes a multiplying phase locked loop (MPLL) clock generator, a transmitter, and a receiver. The MPLL clock generator generates two clock signals and can adjust the phase and frequency difference between them. During testing, the transmitter and receiver can be coupled directly or capacitively, allowing for effective data transmission and reception. The functionality of the receiver is evaluated by comparing the transmitted and received data.
Another significant patent is the "Multiple-input, on-chip oscilloscope." This integrated circuit features a receive data path that equalizes a received analog signal and converts it into digital data values based on a clock signal. The integrated circuit also incorporates an on-chip oscilloscope, which includes comparators, a phase rotator, and an offset circuit. This setup allows for the determination of eye patterns that correspond to the analog signal before and after equalization, which can be correlated with the error rate of the received data.
