Climate change lifestyle narratives among Norwegian citizens: A linguistic analysis of survey discourse

open access: yesEuropean Policy Analysis, Volume 7, Issue S2, Page 386-404, Summer 2021., 2021
Abstract The present study proposes an analysis of climate change (CC) narratives in answers to an open‐ended survey question, where we ask what a climate‐friendly lifestyle may imply. The representative survey has been conducted online by the Norwegian Citizen Panel/DIGSSCORE, located at the University of Bergen. The survey provided 1,149 answers from

10-bit 40MHZ Sampling Rate Pipelined Analog-to-Digital Converter [PDF]

open access: yes, 2011
随着通信技术的发展和数字产品的日益增长,作为连接模拟信号与数字信号的桥梁,ADC在信号处理中越显重要。ADC的种类多种多样,它们的结构限制了速度、精度以及功耗等各方面的性能。因此,不同的ADC在不同应用场合有着特定的优势和市场。流水式ADC由于其速度快、精度较高、功耗相对较小的原因广泛应用于数字通讯领域中。 ADC的速度得益于工艺尺寸的缩小,但是精度却受到了限制。在CMOS工艺中,尺寸下降导致了晶体管的本征增益的衰减;在深亚微米工艺中,器件的匹配系数不是很高,运放会产生较大的失调电压 ...

Design of ECL ternary circuits with symmetrical inputs and outputs(基于对称输入输出的三值ECL门电路设计)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2007
鉴于传统的多值ECL(发射极耦合逻辑)电路需要多个参考源的弊端,提出了采用对称输入输出的ECL电路结构,并设计了构成三值电路完备集的对称输入输出三值ECL文字电路和取大电路,这种电路形式可以减少ECL电路的参考电平数量,并具有更简单的电路结构,电源电压绝对值较低,并且电路功耗也有所降低.
