With the increasing number of cores in chip multiprocessors, the design of an efficient communication fabric is essential to satisfy the bandwidth and energy requirements of multi-core systems. Scalable Network-on-Chip (NoC) designs are quickly becoming the standard communication framework to replace bus-based networks. However, the conventional metallic interconnects for inter-core communication consume excess energy and lower throughput which are major bottlenecks in NoC architectures. On-chip...

We review and analyze the critical features of ultra-short range wireless links. These features will be required for advancing NoC and SoC integration to the next level, as transistor scaling and hetero-integration on silicon substrates are expected to reach their full potential by the end of the decade. Based on published transceiver data, the scalable wireless NoCs for multi-core processors and reconfigurable networks for SoCs are within reach of Si/SiGe BiCMOS technology in the next few techn...

The performance, tunability and efficiency of double gate MOSFET (DG-MOSFET) low noise amplifier (LNA) is investigated. We propose a novel two-stage common source cascode LNA and study its gain switching properties via back gate tuning in 32 nm DG-MOSFETs that leads to variable and reconfigurable device performances not found in comparable amplifiers built with conventional CMOS architectures without additional hardware. The peak gain changes by almost 9 dB from 6 dB to 14.9 dB for back gate bia...

Wireless networks-on-chips (WINoCs) hold substantial promise for enhancing multicore integrated circuit performance, by augmenting conventional wired interconnects. As the number of cores per IC grows, intercore communication requirements will also grow, and WINoCs can be used to both save power and reduce latency. In this article, we briefly describe some of the key challenges with WINoC implementation, and also describe our example design, iWISE, which is a scalable wireless interconnect desig...

Use of unmanned aircraft systems (UASs) for multiple applications is expected to grow dramatically in the coming decades; this fact has motivated this paper's focus on fundamental physical layer characteristics relevant to UAS communications. In the past, for aeronautical communications with high transmitted power levels, narrow signal bandwidths, elevated ground site antennas in open areas, and low duty cycle transmissions, simple models for channel attenuation sufficed. In the future, when UAS...

This paper presents a wireless channel characterization for a short-range, temperate, medium density forest environment. This environment and frequency band have not been thoroughly characterized. We conducted measurements at a center frequency of 5.12 GHz with a 50MHz bandwidth signal and obtained impulse response estimates. Measured results for delay spread are presented; mean root-mean square delay spread values range from 64 to 87 ns, for link distances up to approximately 110 m. Maximum del...

Performance, tunability and efficiency of double gate MOSFET (DG-MOSFET) based power amplifiers (PA) are investigated. Specifically, we propose two different wide-band PA topologies with 45 nm long DG-MOSFET and study their performance via computer simulations. The first one involves a modified Darlington cascode configuration with a peak gain of ∼26 dB for a 3-dB bandwidth ≥ 30 GHz. The gain flatness is less than 20% in this range. The second topology reported is a three-stage common-source wid...

As Network-on-Chip (NoC) architectures become more relevant with an increasing number of cores on a chip, research into emerging technologies and devices to replace power hungry global metallic interconnects has become critical. In this paper, we propose a practical wireless architecture called GLOW, a global wireless interconnect for NoCs. With our ultra-low power transceivers centered at a 100 GHz carrier frequency, we present a wireless topology with a maximum bandwidth of 80 GHz. Both freque...

As recently noted [1], the wireless channel in the very high frequency (VHF) band has not been thoroughly quantitatively characterized for airport surface areas. For future services such as VHF Data Communications, channel characteristics are needed to enable system optimization. Given the narrow bandwidth of VHF communications (25 kHz), channel dispersion is not significant, but propagation path loss is vitally important. This paper serves as a companion paper to our prior work [1] in the area ...

There are several 60 GHz transceiver architectures that have been explored and reported in the past employing the On Off Keying (OOK) Modulation. All of these designs are primarily based on the conventional bulk CMOS architecture. In this paper, we propose a power efficient double gate (DG) MOSFET based OOK Transmitter in 32 nm DG FinFET technology. The proposed novel OOK modulator consists of only two DG-MOSFETs, making the circuit extremely power and area efficient. The LC oscillator can be tu...
