在制卡和会员卡制作过程中由张力控制器来控制制卡和会员卡制作张力的恒定,是套印准确的关键所以,张力控制系统是任何卷筒制卡和会员卡制作机的一个重要机构,它在很大程度上决定印品的套印准度,张力控制机构主要设于放料部分,制卡和会员卡制作工位和放收料牵引及收卷机构、料卷输出需要阻力,料卷转动有惯性,卷料自身也存在一定的张力值,加上制卡和会员卡制作速度的拉力牵引,制卡和会员卡制作过程中各色组套印对被印材料的阻力使得放卷、制卡和会员卡制作、收卷机构的张力控制显得尤为重要,张力控制的大小应视材料的厚薄、质料宽窄来决定。

A novel layout of IC transformer is proposed to achieve both high turn ratio and coupling coefficient in this paper. In order to discuss the coupling coefficient, the layouts are designed with different turn ratio. The thesis is mainly includes of three experiment topics. The multi-stack structure is proposed to achieve prior goal in first topic. Two groups of proposed devices are designed to maintain identical self- inductances in transformer's primary and secondary coils. Total six devices are fabricated in foundry 90-nm CMOS technology. Using the 9 and 5 metal layers in primary and secondary coils in a specific layout, measurement results show that the transformer has the largest benefit using the bottommost return layer in layout design. In one word, the adoption of more metal layers to construct different turn ratio transformer shows not only improving the N value but also saving the chip area in this experiment.

中文摘要本文是针对不同圈数比变压器探讨其耦合量的变化,并且期望其变压器能同时达到高圈数比及高耦合系数的特性,本论文主要可分为三个实验主题,首先第一个主题提出以90nm CMOS制程技术实现的多层金属层的布局方式,并以相同的一、二次侧自感值分为两组,利用不同返回层来达到不同的圈数比,且从量测结果可以得知,在变压器布局设计上使用最底金属层来作返回层会得到较好的特性,最后从此实验得知一结论,利用合适的多层金属架构达到不同的圈数比,不仅可以改善圈数比,还可以缩小晶片面积。
