Title: The Innovative Mind of Christopher Lam: A Patented Vision in Frequency Control
Introduction: Christopher Lam, an inventor based in Rowland Heights, CA, has made significant strides in the field of electronic engineering. His innovative solutions focus on enhancing the functionality of phase-locked loops (PLLs) through advanced techniques in frequency band selection.
Latest Patents: Christopher Lam holds a patent for a "Phase-locked loop with self-selecting multi-band VCO." This invention offers techniques to effectively select the appropriate frequency band for use in a PLL, optimizing the performance of a multi-band voltage-controlled oscillator (VCO). The design incorporates a detector, a loop filter, the multi-band VCO, and a control unit. The detector receives a primary signal that needs to be locked and a secondary signal related to the VCO signal, providing a crucial output. The loop filter processes this output to generate a control signal, while the multi-band VCO selects one of the numerous frequency bands based on a selection signal, delivering a VCO signal at a frequency determined by the control signal. Furthermore, the control unit derives the selection signal from information sourced from a third signal—a filtered version of the control signal—and a timing signal from a timer unit.
Career Highlights: Christopher is a pivotal member of RF Micro Devices, Inc., where he contributes to the development of advanced communication technologies. His work at this notable firm reflects both his ingenuity and commitment to pushing the boundaries of electronic design.
