110016: Temperature Compensation for Floating-Gate Memory Circuit

Nonvolatile computer memory is a type of memory chip that retains its data even when its power supply is turned off. One example is the erasable, programmable read-only memory chip (EPROM). Nonvolatile memory can store multiple bits per cell by storing a range of charge levels in a floating-gate analog memory cell. One of the challenges of floating-gate...

060129: Multiple-Input Multiple-Output Analog-to-Digital Converter

On-chip signal compression is one of the key technologies driving development of energy efficient biotelemetry devices. Michigan State University’s technology is a novel architecture, called multiple-input multiple-output (MIMO), for analog-to-digital conversion that combines sigma delta conversion with the spatial data compression in a single...

06098: Method and Apparatus for Autonomous Self-Powered Integrated Piezo-Floating Gate Sensors

Each year, hundreds of thousands of hip and knee replacement surgeries are performed in the United States. Most of these prosthetic implants are expected to last for at least 20 years after which revision and replacement surgery will be required. In many cases, however, excessive wear and loosening of artificial joints leads to joint swelling, bone...
