Title: Boon-Aik Ang: Innovator in Phase-Locked Loop Circuits

Introduction

Boon-Aik Ang is a prominent inventor based in Santa Clara, CA (US). He has made significant contributions to the field of electronics, particularly in the area of phase-locked loop circuits. With a total of 17 patents to his name, Ang has established himself as a key figure in innovation.

Latest Patents

Among his latest patents is a groundbreaking invention titled "Reference clock switching in phase-locked loop circuits." This patent describes 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 "Spur cancelation in phase-locked loops using a reconfigurable digital-to-time converter." This invention addresses deterministic jitter in clock signals generated by fractional-N phase-locked loop circuits. A cancelation circuit generates a feedback signal by delaying an output signal from the divider circuit. The delay is based on accumulated phase residue from the modulation of the frequency divisor. The feedback signal is then compared to a reference signal, which helps adjust the oscillator circuit generating the clock signal, effectively reducing deterministic jitter.
