On-chip graphene resonators for digitally controlled and widely tunable RF sensing

Summary

James Hone, Ph.D.

Technology Benefits

Dramatically lowered area, cost and power requirements compared to existing technologyCan be easily constructed on CMOS using past-proven and ubiquitous fabrication processes such as dry polydimethylsiloxaneCombines high frequency with large mechanical compliance, greatly increasing tunability over current silicon resonator technologyDisplays zero-bandgap semiconducting properties with mobility up to 120,000 cm2/V-s and Q factors greater than 1000 at room temperatureCan adjust the center or matching frequency with greater flexibility to achieve higher mixer linearity with enhanced out-of band rejection on RF portCompatibility with existing circuitry techniques such as dual path noise canceling and higher order filter architecturesPatent information:Patent PendingTech Ventures Reference: IR CU14172

Technology Application

Low-power, portable wireless networks in almost any field including industrial monitoring, building automation, asset management, environmental monitoring, Bluetooth or wireless USB, radios, medical diagnostic and treatment instruments, and cellphones among othersIncreasing the strength, durability, and flexibility of wireless communication devices.
