A two-stage amplifier, operational at 0.8V and drawing 7/spl mu/A, has been integrated in a standard digital 0.18/spl mu/m CMOS process. Rail-to-rail operations at the input are enabled by complementary transistor pairs with g/sub m/ control. The efficient rail-to-rail output stage is biased in class AB. The measured DC gain of the amplifier is 75dB, and the unity-gain frequency is 870kHz with a 1

Analyses of economic actions often proceed from a consideration of how trust serves as a basis for the interaction of economic agents. A bankruptcy entails a breach of the relations of trust in an economic network. Receivers are the lawyers appointed by Swedish courts to investigate and ultimately resolve bankrupts disputes. The article demonstrates how the manner in which receivers characterise t

This thesis deals with the expression of pituitary adenylate cyclase activating peptide (PACAP) in sensory C-type cells and primary afferent fibres and its possible role in nociceptive transmission. PACAP-expression, -release, -synthesis and -function were investigated in a series of measurements using immunocytochemistry, radioimmunoassay, in situ hybridization histochemistry, Northern blot, elec

This paper deals with the considerable membership shifts between the Swedish union confederations LO (blue-collar), TCO (white-collar) and Saco (white-collar), but above all it is about the rising share of union members in occupational/professional unions in the last few decades. This development corresponds to Saco's increased share of union members (8 per cent in 1990, 15 per cent in 2008). Also

Surface processes play a large role in the growth of semiconductor nanowires by chemical beam epitaxy. In particular, for III-V nanowires the surface diffusion of group-III species is important to understand in order to control the nanowire growth. In this paper, we have grown InAs-based nanowires positioned by electron beam lithography and have investigated the dependence of the diffusion of In s

Abstract in UndeterminedSometimes energy security is used as an advocacy for renewable energy systems. Although renewable energy systems can surely have such characteristics they will not per se solve all types of security problems, and new problems will most certainly arise. In this paper, energy security aspects of renewable energy systems are analysed taking the starting point in a broad typolo

Rapporten behandlar marknadens möjligheter och begränsningar inom välfärdsområdet både vad gäller finansiering och produktion. Finansieringsaspekten handlar om möjligheterna till ökat inslag av försäkringar avseende t.ex. sjukfrånvaro, arbetslöshet, sjukvård och äldreomsorg. Produktionsaspekten handlar om möjligheterna att intensifiera konkurrensen inom en rad områden som exempelvis skola, vård,

The increasing number of mobile devices and high-speed services accelerate the growth of traffic in cellular backhaul networks. The traditional technologies used in the backhaul, copper, radio links and optical fibers, either cannot offer high data-rate, or are expensive. In this paper, we propose mixed integer programming models to facilitate upgrading the cellular backhaul using the free space o
