This paper compares two different sampling techniques, charge sampling and conventional voltage sampling. Theoretical analysis and circuit simulation show some attractive advantages of charge sampling over voltage sampling. High speed charge sampling, charge sub-sampling, and charge sampling with embedded filter functions are proposed in this paper.

Popular Abstract in Swedish I dagens nya cellulära kommunikationssystem betraktas användandet av multipla mottagarantenner i kompakta användarterminaler som en nödvändighet för att kunna utnyttja fördelarna med diversitet och MIMO (Multiple Input Multiple Output) teknik och därmed uppnå god celltäckning och hög dataöverföringshastighet. Den senaste utbyggnaden av det cellulära kommunikationssystemCo-band multiple-antenna implementation in compact user terminals is necessary for harvesting the full potential of diversity and multiple-input multiple-output (MIMO) technology in cellular communication systems. The recent worldwide deployment of Long Term Evolution (LTE), which requires the use of MIMO technology in the downlink, adds to the urgency of achieving both practical and optimal multi

The long-term effects of the active accelerator pedal were evaluated in the city of Lund in 2000 and 2001. The system, installed in 284 vehicles, produced a counterforce in the accelerator pedal at the speed limit. It could, however be overridden by pressing the accelerator pedal harder. The results showed that test drivers’ compliance with the speed limits improved considerably. Reduction in aver

Background: Alexithymia is a disturbance associated with psychosomatic disorders, pain syndromes, and a variety of psychiatric disorders. The Affect School (AS) based on Tomkins Affect Theory is a therapy focusing on innate affects and their physiological expressions, feelings, emotions and scripts. In this pilot study we tried the AS-intervention method in patients with chronic benign pain. Metho
