Mr. Patterson's research focuses on circuit and instrument design for a variety of applications. Most recently those applications include circuits for implantable neural sensors to do chronic recording in the cortex, for studies of the limiting factors in CMOS transistor sizing, and for microphone-array applications.
William R. Patterson III is a Senior Lecturer and Senior Research Engineer in the Division of Engineering. His current research focuses on circuit and instrument design for implantable neural sensors and for studies of aggressively scaled CMOS transistors. His work on neural recording from the motor cortex of primates and humans centers on the design of custom integrated circuits to move all electronics for signal capture and processing inside the skull. A multi-amplifier custom integrated circuit mounts on the back of an array of extra-cellular microprobes. Depending on the application, the circuit is powered optically or by RF and data returns by infrared link either over fiber or transcutaneously.
