Title: The Innovations of Ernest W Cordan, Jr.

Introduction

Ernest W Cordan, Jr. is a notable inventor based in Colorado Springs, CO. He has made significant contributions to the field of integrated circuit technology, holding a total of three patents. His work focuses on enhancing the performance and reliability of serial bus systems.

Latest Patents

Cordan's latest patents include an "Integrated circuit driver for serial bus having output overvoltage." This invention features a driver that comprises first and second current sources connected to high and low voltage sources, respectively. It also includes first and second transistor circuits designed to block voltage spikes that exceed the voltages provided by the high and low voltage sources. The configuration ensures that the first current source and the first transistor circuit are series connected between the high voltage supply and the high line, while the second current source and the second transistor circuit are series connected between the low voltage source and the low line.

Another significant patent is the "Matched current source serial bus driver." This circuit provides time and magnitude matched currents as sources and sinks to a pair of serial bus lines. A reference current path is established in transistors that are structurally mirrored to the devices sourcing and sinking bus line currents. The time-regulated switching of the reference current ensures RF suppression while maintaining the match of the source and sink current sources driving the bus. Additionally, selective decoupling during a loss of circuit ground condition eliminates spurious injection of current into either bus line.
