Title: Michael E Harrell: Innovator in Circuit Design
Introduction
Michael E Harrell is a notable inventor based in Colorado Springs, CO (US). He has made significant contributions to the field of circuit design, holding a total of 4 patents. His work focuses on enhancing the performance and reliability of digital to analog converters and related systems.
Latest Patents
One of his latest patents is titled "Closed loop DAC artifact generation." This invention involves a circuit supply system that includes a main digital to analog converter (DAC) circuit designed to produce a direct current (DC) output level at a system output. The system features a feedback circuit path connected to the output, along with a primary control circuit path that regulates the DC output level using the main DAC circuit and the feedback circuit path. Additionally, a secondary control circuit path is included to add a non-DC signal component to the DC output level, which is also regulated using the feedback circuit path.
Another significant patent by Harrell is "Output voltage glitch reduction in test systems." This invention describes a clamp circuit that comprises an output transistor and a replica transistor coupled as a current minor pair. The replica transistor is scaled in size to the output transistor by a size ratio. A first current source is configured to set a current in the replica transistor, ensuring that the output current is clamped at a specific value. The register circuit stores a value that sets this clamped output current.
