Title: Innovator Spotlight: William D. Elliott

Introduction: William D. Elliott, based in Sunnyvale, CA, is a prolific inventor with a remarkable portfolio of three patents. His innovative contributions have significantly advanced the field of digital signal processing, showcasing his expertise in designing systems that efficiently manage signal phase and frequency.

Latest Patents: Elliott's most recent patent, titled "Digital Phase Lock Loop," presents a system constructed from an all-digital circuit implementation and standard cell construction. This digital phase lock loop (PLL) features a digital frequency synthesizer and a digital phase detector. The synthesizer employs a digital delay-locked loop (DLL) with multiple delay chains, each incorporating digitally programmable delay elements. This configuration allows for phase locking with an input reference signal. Notably, the design includes a non-glitching multiplexer (MUX) that selects a pulse glitch-free from the chosen output tap and a phase accumulator that can precisely divide the timing period of the input reference signal.

Another noteworthy patent by Elliott is the "System for High Precision Signal Phase Difference Measurement." This integrated circuit device excels in accurately comparing the relative phase of two signals. The invention includes delay chains that receive and delay the first and second signals. At the core of the system are symmetrical Flip-Flops that determine the arrival time of the edges of each signal, enabling precise phase comparison.
