Title: The Innovations of William H. Gulliver

Introduction

William H. Gulliver is a notable inventor based in Gilbert, AZ (US). He has made significant contributions to the field of electronics, particularly in the development of phase-locked loop systems. With a total of 5 patents to his name, Gulliver's work has had a lasting impact on the industry.

Latest Patents

One of Gulliver's latest patents is titled "Circuit and method for compensating a phase detector." This invention relates to a Phase Locked Loop (PLL) system that provides signals UP and DOWN for a charge pump. The charge pump supplies a biasing signal to a voltage-controlled oscillator. The phase and frequency relationship between a feedback signal from the voltage-controlled oscillator and a clock signal are utilized by a compensating phase-frequency detector to generate the signals UP and DOWN. The pulse width of the signal DOWN is limited when a transition of the clock signal is missed. An error detector provides a signal BADCLK after detecting that multiple transitions of the clock signal have been missed. The signal BADCLK generates the signal UP, which has a pulse width that compensates for the last signal DOWN and keeps the biasing signal to the voltage-controlled oscillator relatively constant when the clock signal fails.

Another significant patent focuses on minimizing recovery time. This circuit includes a reset stage and a Phase-Locked Loop (PLL) device. The PLL device consists of a phase detector, a charge pump, a filter, and a voltage-controlled oscillator. The reset stage receives a reference signal and is connected to the phase detector. The phase detector receives the reference signal and a feedback signal. When the reference signal switches from a first clock signal to a second clock signal, the reset stage places the phase detector in an inactive state until it detects a falling edge in the reference signal.
