Title: Mark R Shaffer: Innovator in Integrated Circuit Design

Introduction

Mark R Shaffer is a notable inventor based in Culpeper, Virginia. He has made significant contributions to the field of integrated circuit design, holding two patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is for a Clock Phase Control circuit. This invention includes a clock input gate module, first and second shift register divider modules, and a multiplexer. The clock input gate module is designed to produce first and second intermediate clock signals based on an oscillating input clock signal. The first shift register divider module generates at least one first phase clock signal with a different frequency than the first intermediate clock signal. Similarly, the second shift register divider module produces at least one second phase clock signal with a different frequency than the second intermediate clock signal. The multiplexer then selects one of the first or second phase clock signals to produce an output clock signal.

Another significant patent by Shaffer is a Method for Radiation Hardening of Integrated Circuits. This invention is an IC design enhancing tool that automatically reviews and environmentally hardens an IC design layout. The tool scans through an IC netlist generated by an electronic design automation (EDA) tool and replaces non-compliant components with hardened ones. This iterative process continues until the final design layout meets the required hardening criteria.
