Title: The Innovations of Robert Leonard Pritchett

Introduction

Robert Leonard Pritchett is a notable inventor based in Bath, PA (US). He holds a total of 7 patents that showcase his contributions to the field of integrated circuits and frequency detection technologies. His work has significantly impacted the development of electronic systems.

Latest Patents

One of Pritchett's latest patents is the Harmonic Lock Detector. This integrated circuit is designed to detect the harmonic lock of a phase-locked loop. It includes a frequency synthesizer that receives a reference clock signal and generates an oscillator clock signal. A phase generator then takes the oscillator clock signal to produce a phase of that signal. Additionally, a shift register receives the reference clock signal and is clocked by the phase of the oscillator clock signal, resulting in a repetitive sequence of logic states. In an alternate embodiment, a harmonic decode circuit decodes the shift register output to determine which harmonic the phase-locked loop has locked onto.

Another significant patent is the Wide Range Digital Frequency Detector. This integrated circuit generates an oscillator clock signal based on a reference clock signal and features a wide band digital frequency detector. The detector includes a first shift register clocked by the reference clock signal and a second shift register clocked by the oscillator clock signal. A third shift register receives input from the first shift register and is clocked by the output of the second shift register, providing a first oscillator control output. A fourth shift register receives a phase of the reference clock signal and is clocked by the oscillator clock signal to provide a second oscillator control output. In an alternate embodiment, the first oscillator control output is coupled as the up-down control input of an up-down counter, while the second oscillator control output is coupled as the clock input to control the oscillator clock frequency.
