This paper presents an overview of technical challenges in achieving higher integration levels, lower power dissipation, smaller form factor, and lower cost in portable battery-powered RF transceivers for personal communications applications. Specific emphasis is placed on silicon integrated circuits for transceivers in the 800MHz-2.5GHz range of frequencies.

The maxima of the scalar dissipation rate in turbulence appear in the form of sheets and correspond to the potentially most intensive scalar mixing events. Their cross section extension determines a locally varying diffusion scale of the mixing process and extends the classical Batchelor picture of one mean diffusion scale. The distribution of the local diffusion scales is analyzed for differen...

A 90nm CMOS, 64Kbit, 1.16GHz, 16 port SRAM with multi-bank architecture realizing 590Gbps random access bandwidth, 41mW power dissipation at 1GHz and 0.91mm2 (13.9μm2/bit) area consumption is reported. Compared to conventional 16 port SRAM data, area and power consumption are reduced by factors 16 and 5, respectively, while maximum clock frequency is about a factor 2 higher.

Abstract Up until now, ground state cooling using optomechanical interaction is realized in the regime where optical dissipation higher than mechanical dissipation. Here, we demonstrate that a continuous system possible by backward Brillouin scattering while exceeds which common case waveguides. The achieved an anti-Stokes process modulating intensity of coupling via pulsed pump to suppress hea...

In this work we study the fluctuation and dissipation of a string attached to brane in deformed backreacted AdS-Schwarzschild spacetime. This space is solution Einstein-dilaton equations contains conformal exponential factor exp?(k/r2) metric. We consider backreaction contributions coming only from warp on black hole, where are probe approximation. Within Lorentz invariant holographic model hav...

This paper presents analytical models, as well as numerical and experimental verification of intrinsic dissipation due to thermoelastic loss in tuning-fork resonator. The thermoelastic analytical governing equations are created for resonator vibrating at drive-mode and sense-mode, and thermoelastic vibration field quantities are deduced. Moreover, the theoretical values are verified that coinci...

We study the pair production of open strings in constant external electric fields, using a general framework which encodes both relativistic string theory and generic linearly extended systems as well. In the relativistically invariant case we recover previous results, both for pair production and for the effective Born-Infeld action. We then derive a non-relativistic limit where the propagatio...
