Dynamic Range of Nanoresonators on Par With Animal Hearing

Atomically thin membranes enable nanoresonators to achieve extraordinalry wide dynamic range for tiny machines Image: Case School of Engineering/Case Western Reserve University Researchers at Case Western University have fabricated nanoelectromechanical system (NEMS) resonators made from molybdenum disulfide that have an extraordinarily broad dynamic range. These nanoscale devices’ range is roughly comparable…

PAM4 Demands Accurate S-parameters

PAM4 challenges signal integrity, test, and design engineers who are responsible for SERDES (serializer/deserializer) components, interconnects, backplanes, cables, connectors, circuits, and complete systems. As high speed serial data rates advance from 15 Gb/s to beyond 50 Gb/s, we face a fundamental shift. Conventional logic-emulating NRZ (Non-Return to-Zero) signaling is being…
