Title: Frederick Alan Williams: Innovator in Switching Regulators and Digital Phase Detection
Introduction
Frederick Alan Williams is a notable inventor based in Bellevue, WA (US). He holds 2 patents that showcase his contributions to the fields of electronics and signal processing. His work has significantly impacted the design and functionality of various electronic devices.
Latest Patents
Williams' latest patents include a Transformerless Switching Regulator with Controllable Boost Factor. This invention allows a current-mode controlled boost converter to operate based on current sensing through a switch to ground, facilitating the use of common controllers. To prevent reverse current from a cascaded charge pump, the input of the charge pump is blocked by a diode, ensuring efficient operation. Another significant patent is the High Resolution Digital Phase Detector. This device is designed to receive a threshold value and a sequence of digital samples from an analog video signal. It provides a first output signal when a digital sample crosses the threshold value and performs interpolation to resolve the crossing time to a subpixel level. The second output signal represents a fractional phase error, which is crucial for synchronizing the output of a voltage-controlled oscillator with the incoming analog video signal.
