Title: John H Guilford: Innovator in Phase Accumulation and Digital Stimulus Response

Introduction

John H Guilford is a notable inventor based in Stanwood, WA (US). He holds a total of 11 patents that showcase his contributions to technology, particularly in the fields of phase accumulation and digital stimulus response.

Latest Patents

One of his latest patents is titled "Continuous phase maintenance for switched frequencies using phase accumulators." This invention involves an integrated phase accumulator apparatus that includes a first and a second phase accumulator, along with a switch. The first phase accumulator is designed to accumulate a first phase increment over time, providing a first accumulated phase value for signal generation via a local oscillator at a first frequency. The second phase accumulator serves a similar purpose for a second frequency. The switch facilitates the transition between the two frequencies while maintaining continuous phase for both.

Another significant patent is "Multi-bank digital stimulus response in a single field programmable gate array." This apparatus efficiently moves stimulus and response data between memory and a device under test (DUT) across multiple data transfer banks. In one mode, the banks output stimulus data to the DUT as independent channels, while in another mode, they combine the data into a single bank for streamlined processing.
