60 GHz Second Harmonic Power Amplifiers in 130-nm CMOS

Abstract—Two different frequency doubling power amplifiers have been measured, one with differential and one with single-ended input, both with single-ended output at 60 GHz. The amplifiers have been implemented in a 1p8M 130-nm CMOS process. The resonant nodes are tuned to 30 GHz or 60 GHz using on-chip transmission lines, which have been simulated in ADS and Momentum. The measured input impedan

"Använd principer för framgångsrika köpcenter"

Politiker och kommunala tjänstemän i Malmö har förväxlat vad de själva önskar med hur människor faktiskt beter sig. Det skriver Johan Anselmsson, docent inom handel på Ekonomiskolan vid Lunds Universitet

Primary structure of bovine vitamin K-dependent protein S

Protein S is a vitamin K-dependent plasma protein that functions as a cofactor to activated protein C in the inactivation of coagulation factors Va and VIIIa. The nucleotide sequence of a full-length cDNA clone, obtained from a bovine liver library, was determined and the amino acid sequence was deduced. In addition, 95% of the structure was determined by protein sequencing. Protein S consists of

Fuel Dependent Heat Release Differences between Euro Diesel Fuel and RME in a HSDI Diesel Engine

In the degree that costs and demand of crude oil rise, diminish the economical disadvantages for alternative Diesel fuels, resulting in a variety of feasible substitutes. Diesel fuel substitutes have deviating exhaust emissions from conventional fuel. The methyl ester of rapeseed oil (known as RME/Biodiesel) is receiving increasing attention as an alternative fuel for Diesel engines. RME is a non-
