Title: The Innovations of Michael A McCullough
Introduction
Michael A McCullough is a notable inventor based in Pasadena, CA. He holds a total of four patents, showcasing his contributions to the field of technology and engineering. His work primarily focuses on advancements in clock de-skewing apparatuses for data processing systems.
Latest Patents
One of his latest patents is the "Automatic clock de-skewing apparatus." This invention provides automatic clock de-skewing for multiple circuit boards within a data processing system. Each circuit board is designed with multi-layer construction and includes a clock distribution chip that features on-chip automatic clock de-skewing circuitry. This circuitry ensures that de-skewed clocks are provided to other chips on the circuit board. The implementation of feedback circuitry, which includes a multi-tapped delay line and an accurate reference delay, is crucial for the automatic provision of de-skewed clocks at the outputs of the clock distribution chip. The accurate reference delay is effectively provided by a strip transmission line formed in a conductive layer of the multi-layer board.
