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。

测井曲线的值是深度的函数，测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢，在某一范围内，当一阶导数呈现符号转换时，相对应的深度点的测井值即为该范围内极大值；测井曲线的二阶导数则表示曲线的凹凸性，在某一范围内，当二阶导数呈现符号转换时，相对应的深度点代表了测井曲线的拐点，即反映曲线凹凸性变化的转折点，亦即地层的分界面。

将定子一种极数的磁场感应于转子绕组中的电流，通过集电环和电刷，但由另一种极数的磁场感应的电流，却自动流经另一闭合回路，而不通过集电环和电刷：于是，如果后一种极数是电动机的工作基波磁场，而把前一种极数作为用以起动的谐波磁场，则可以把起动电阻直接焊接在转子绕组上，而把集电环和电刷取消，从而出现了转子电路上无集电环、无电刷、无触点的谐波起动绕线型感应电动机。

The horizontal and vertical first derivatives of magnetic anomalies of an infinite cylinder are calculated by the cosine transform method, in which the maximum errors are -0.28 nT/m and 0.47nT/m, respectively and the percent errors are generally within -3.57%~3.27% and -1.94%~1.88%, respectively except several data of the boundary and part are bigger because of remains of Gibbus effect. The calculating curve and theoretical curve are approximately coincident, and there is no influence by effective magnetic dip angle in computing. But the errors with the Fourier transform method are -10.62nT/m and 14.42nT/m, there is large departure between the calculating curve and theoretical curve and evident influence by effective magnetic dip angle in computing.
