1/f Noise Characterization in CMOS Transistors in 0.13um Technology

Low-frequency noise has been studied on a set of n- and p-channel CMOS transistors fabricated in a 0.13mum technology. Noise measurements have been performed on transistors with different gate lengths operating under wide bias conditions, ranging from weak to strong inversion. Noise origin has been identified for both type of devices, and the oxide trap density Nt, the Hooge parameter alphaH and t

Impact of user on the multiplexing efficiency of a MIMO terminal antenna

Abstract in UndeterminedThis study investigates the impact of user on the multiplexing efficiency of a pentaband two-element MIMO terminal antenna. At the 750MHz band, the results show that the antenna total efficiency decreases by 4 dB in the presence of the user hand. However, this negative effect is partly compensated by the de-correlation effect of the hand. As a result, the multiplexing effic

Libellus de Magno Erici Rege

The anonymous Libellus de Magno Erici Rege gives an outline of King Magnus Eriksson’s reign, painting it in dark colours. The author emphasises that Sweden is an elective, not a hereditary kingdom, and that the king can be deposed if he commits evil deeds and turns into a tyrant. The detailed account of King Magnus’s reign is designed to show that he had wilfully and systematically broken the law,

Control Signal Constraints and Filter Order Selection for PI and PID Controllers

Large control signal derivatives or inter-sample differences may harm actuators. An optimization constraint limiting such variations, related to measurement noise, is derived. Using the constraint, optimal PI, PID and measurement filters with different orders are designed for several processes and compared to the optimal linear controller of high order found via Youla parametrization.

Dislodging Butterflies from the Supervenient

Not all areas in value theory are battlegrounds. We find, for instance, a strong consensus when it comes to whether or not values are so-called supervenient properties, i.e., properties that accrue to the value bearer in virtue of some or all of its other kinds of (subvenient) properties. These ‘other properties’ are often assumed to belong (at least at some basic level) to the object’s so-called
