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。

Results: The prevalence rates within two weeks among the elderly were 29.7% and 64.7%, and the rates of seeing a doctor within two weeks were 9.5% and 34.7% in urban community and rural areas respectively. The prevalence rates of chronic diseases were 62.1% and 56.4% in city and rural area respectively. Sixty-six point nine percent of the elderly in urban community went to high-level hospitals for medical services, while 73.3% of old people in rural area went to village clinics. The main reasons for diseased people not to visit a doctor were self feeling of slight illness (21.7%) and self-treatment (51.6%) in urban community and were low income (40.8%) and self feeling of slight illness (25.9%) in rural areas. The main affecting factors to rates of seeing a doctor within two weeks were increased age and family income per capita among the elderly in urban community, and were suffering or not suffering from chronic diseases in rural area.

结果：城市和农村社区老年人的两周患病率分别为29.7%和64.7%，两周就诊率为9.5%和34.7%，慢性病患病率分别为62.1%和56.4%；城市老年人就诊地点主要以县市级和省级医院为主，两者所占比例为66.9%；农村则以个体诊所或村卫生室为主，占73.3%；两周患者未就诊原因在城市主要是自感病轻（占21.7%）和自我医疗（占51.6%），在农村主要为经济困难（占40.8%）和自感病轻（占25.9%）；影响老年人两周就诊的因素在城市为年龄和家庭人均月收入，在农村是患慢性病与否。
