Title: Simon C. Leung: Innovator in Phase-Locked Loop Technologies
Introduction
Simon C. Leung is a notable inventor based in Markham, Canada. He has made significant contributions to the field of electronics, particularly in the development of phase-locked loop technologies. With a total of 2 patents to his name, Leung's work has had a considerable impact on the industry.
Latest Patents
Leung's latest patents include innovative techniques aimed at enhancing the performance of electronic systems. One of his patents focuses on a phase offset cancellation technique for reducing low-frequency jitters. This invention involves a phase-locked loop that utilizes a phase-frequency detector to provide pulse signals proportional to phase differences between two signals. The apparatus introduces a relative phase difference between a first clock signal and a second signal, which is synchronized with the output signal of the loop. Additionally, it includes mechanisms for offsetting the effects of the introduced phase difference and obtaining a loop control voltage from the charge pump.
Another significant patent by Leung is a voltage to current converter with independent loop gain and frequency. This converter consists of a first current steering mirror that converts an input voltage signal into an output current. It also features a second current mirror that generates a selectable output current. The combined output currents are then used to control a current-controlled oscillator, which can be integrated into a phase-locked loop.
