Suspended Spot‐Size Converters for Scalable Single‐Photon Devices

High-quality multiterminal suspended graphene devices.

We introduce a new scheme to realize suspended, multiterminal graphene structures that can be current annealed successfully to obtain uniform, very high quality devices. A key aspect is that the bulky metallic contacts are not connected directly to the part of graphene probed by transport measurements, but only through etched constriction, which prevents the contacts from acting invasively. The...

POINT OF LOAD CONVERTERS - The Topologies, Converters, and Switching Devices Required for Efficient Conversion

Point of load (POL) or point of use (POU) converters are emerging as the popular solution for applications in which circuits require low voltages of 3.3 V and below. The demand for these types of voltage levels stems from the requirement for lower core voltages, and it is obvious that the current capability for these converters will increase even if the power capability stays the same. This has...

Scalable, high-performance magnetoelastic tags using frame-suspended hexagonal resonators

This paper presents the analysis, design and experimental evaluation of miniaturized magnetoelastic tags using frame-suspended hexagonal resonators. Magnetoelastic tags—also known as acousto-magnetic or magnetomechanical tags—are used in wireless detection systems—for example, electronic article surveillance and location mapping systems—that electromagnetically query the resonant response of th...
