Title: Robert David Froggatt: Innovator in Injection Locking Oscillators
Introduction
Robert David Froggatt is a notable inventor based in Cork City, Ireland. He has made significant contributions to the field of electronics, particularly in the development of injection locking oscillators. With a total of 2 patents to his name, Froggatt's work has garnered attention in the industry.
Latest Patents
Froggatt's latest patents include innovative technologies that enhance the functionality of oscillators. One of his patents is for an "Injection locking oscillator with phase rotation capability." This system comprises an oscillator and an injection circuit that is coupled to the oscillator. The injection circuit features a first injection branch that receives a first clock signal and generates a first injection current based on that signal. Additionally, a second injection branch is configured to receive a second clock signal, generating a second injection current, which is then combined at a node with the first injection current.
Another significant patent is for "Random mismatch compensation for high frequency injection locking ring oscillators." This invention includes a plurality of delay elements connected in a loop and coupled to a global power supply. Each delay element is driven by a preceding stage and drives the next stage. The system also incorporates voltage control circuits, a phase comparator, and a controller, all working together to enhance the performance of the injection-locked oscillator.
