60 GHz 130-nm CMOS Second Harmonic Power Amplifiers

Abstract—Two different frequency doubling power amplifiers have been measured, one with differential and one with singleended 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 impedance

Systematics of Lactobacillus spp. of probiotic potential

Lactobacillus is a heterogeneous bacterial genus comprising at present 91 species. The high species number often makes classification and identification difficult, especially as the taxonomy to a high degree has been based on phenotypical traits. Members of the genus are of commercial importance, involved in a range of industrial products and applied as probiotics, “live microorganisms which when

The ethical contract as a tool in organic animal husbandry.

This article explores what an ethic for organic animal husbandry might look like, departing from the assumption that organic farming is substantially based in ecocentric ethics. We argue that farm animals are necessary functional partners in sustainable agroecosystems. This opens up additional ways to argue for their moral standing. We suggest an ethical contract to be used as a complementary to t

Solid Oxide Fuel Cell Auxiliary Power Units for Heavy Duty Trucks

This paper explores the potentials of solid oxide fuel cells (SOFCs) as 3 kW auxiliary power units for trucks and military vehicles operating on diesel fuel. Various issues are discussed, e.g., the requirements and specifications for the unit as well as the advantages, challenges, and development issues for SOFCs in such applications. System design and analysis are carried out. The major component
