This paper examines the impact of mutual inductance and parasitic capacitance on the phase-error performance for a class of CMOS quadrature voltage-controlled oscillators (QVCOs). Good agreement is found between theory, post-layout simulations, and measurement results. The QVCOs were implemented in a standard 0.35/spl mu/m CMOS process. All QVCOs display a center frequency of 2 GHz and a tuning ra

The first time I visited, what is sometimes called the last Hawaiian fishing village, Miloli´i, South Kona, on the west coast of the island of Hawaii (The Big Island) in 1998, a villager took me out for fishing. We had a pretty decent catch of tuna that morning, she told me. Back to the house my newly found friends were soon preparing for a wonderful lunch with fresh tuna. Or, so I thought. To my

Purpose : to gain knowledge on how managers experience organizational core values, and to explore how the managers look upon the significance of such values in relation to their leadership. Theoretical framework : organisational culture (Schein) and action theory (Argyris & Schön). Regarding values, social influence and theories on motivation, studies by Rokeach , Sheldon and Elliot. Theory

It has often been argued that the Earth is like an island in space and that its brittleness is most clearly reflected on small islands in the oceans. Easter Island, in particular, with its largely depleted resources, has been seen as a microcosmic warning about what could happen to our entire planet. However, the analogy of the Earth and islands with finite natural resources is not self-evident fr

Marine invertebrates and seaweeds of the lagoons and reefs have always been an important source of food and raw materials for the people of Oceania. I examine the gathering of these organisms in both contemporary and more ancient contexts, and according to a gender-based division of tasks. It is argued that although men’s fishing has been well documented, until fairly recently women’s inshore fish

The aim of the study was to explore the possibility of obtaining a helical CT scan of a long segment of vertebral column, optimally reduce the radiation dose, compare the radiation dose of the low dose helical CT with that of some of the CT protocols used in clinical practice and finally assess the impact of such a dose reduction on the image quality. A chest phantom was examined with a 16-slice C

According to medieval canon law, a marriage could be declared invalid if the consent had been given through force or fear. This ruling was a natural consequence of the insistence on free consent as the only requirement for a valid marriage. It did, however, entail a number of both practical and theoretical problems. It could be difficult to prove force and fear within the family, but also to defin
