Analog-to-digital converter (ADC) technologies
Background
Dr. Nan Sun and his research group have developed a portfolio of analog to digital converter (ADC) technologies that are available for licensing. Overall, Dr. Sun’s lab develops high-performance analog/mixed-signal circuits and architectures, with research efforts focusing primarily on designing low-power, high-speed, and high-resolution...

Ultrathin conformal mantle cloaks for invisibility and antenna applications
Background Significant interest in reducing the antenna blockage in high-complexity or crowded communication systems has been recently highlighted by several authors. In this context, reducing the electromagnetic presence of an antenna or a sensor by tailoring its geometry, loading, or cover has been explored and demonstrated in several examples. Recently,...

CSALT: Context switch aware large translation look-aside buffer (TLB)
BackgroundContext Switch Aware Large TLB (CSALT) addresses the problem of increased TLB miss rates and their adverse impact on data caches. The invention proposes to partition the on-chip caches to house translation entries (TLB entries/page table entries) alongside data. The partitioning is achieved by means of a low overhead cache partitioning algorithm...

Very large DRAM-based TLB
Background Cloud services use virtualization platforms to provide their services. These platforms use hypervisors to enable easier scalability of applications and higher system utilization by abstracting the underlying host resources. Unfortunately, these systems have an increased level of memory virtualization pressure, as hypervisors and guests keep...

Ultra-thin IR detector
BackgroundStrained layer superlattices (SLSs) have attracted significant attention as potential light absorbers for infrared (IR) photodetector applications. Such semiconductor-based structures provide effective band gaps across mid-wave to long-wave IR that are tunable by control of layer thicknesses and material composition. Of particular interest...
