A 90 nm CMOS 14.5 GHz injection locked LO generator with digital phase control

A 14.5 GHz Injection Locked Oscillator (ILO) with digital output phase control has been implemented in a 90 nm CMOS process. It is intended for LO signal generation in integrated phased array transceivers. The chip, measuring 360x530 μm2 including pads, was characterized using on-wafer probing. It consumes 9.4 mA from a 1.2 V supply and has a 1.4 GHz frequency range where full 3600 phase range is

An ASIC Implementation for V-BLAST Detection in 0.35um CMOS

The V-BLAST system has been shown to be capable of exploiting the capacity advantage of multiple antenna systems. The square root algorithm for V-BLAST detection is attractive to hardware implementations due to low computational complexity and numerical stability. A low complexity VLSI architecture of the square root algorithm is presented in this paper. The proposed architecture is scalable for v

Stopping in central sqrt(s_NN) = 200 GeV Au+Au collisions at RHIC

In relativistic heavy ion physics, nuclei are collided at large center-of-mass energies and the dynamics of the collision is probed by measuring the produced particles. In the collisions the baryon number of the initial nuclei is conserved. By measuring the baryon rapidity densities and subtracting the anti-baryon rapidity densities it is possible to study the stopping of the participating nucleon

Rethinking User Involvement in the Front End of Healthcare Innovation

The purpose of this paper is to share insights from an empirical study within the Swedish healthcare system, based on a case study of the largest business unit of a Swedish medical technology company and its key customer segment. The study involving a Swedish medical technology company and three Swedish hospitals indicates need to move away from an archetypical, largely homogeneous view of the use

Exploring the interactome of EF-hand proteins

EF-hand proteins are central in many cellular processes being the main group of Ca2+-sensing and buffering proteins in the cell. In the work presented in this thesis we study ligand interactions of three EF-hand proteins; calmodulin, calbindin D28k and secretagogin. We have developed a screening method using proteins arrays and validation of targets with surface plasmon resonance. With have applie
