Title: The Innovations of Stephen Richard Foster

Introduction

Stephen Richard Foster is a notable inventor based in Bishop's Stortford, GB. He has made significant contributions to the field of digital signal processing, particularly through his innovative patent. His work has implications for improving the accuracy and efficiency of phase detection in digital signals.

Latest Patents

Foster holds a patent for a "Method and apparatus for phase detection in digital signals." This invention provides an improved method for detecting the phase difference between a digital data signal and a clock signal. By ensuring that no pulse in the output phase signal is narrow enough to introduce a non-linearity, the invention avoids a common source of non-linearity found in existing phase detectors. Additionally, the design ensures that critical timing paths through the circuit contain similar circuit blocks with comparable propagation delays, preserving relative time relationships from clock and data inputs to XOR inputs. This circuit is largely insensitive to changes in component characteristics, provided they move together, as would be the case in an integrated circuit implementation. Foster's patent represents a significant advancement in the field.
