Abstract
Inductors and transformers are essential building blocks in many circuit applications, including wireless power transfer and Radio Frequency (RF) Integrated Circuits (IC). Their design process is often unsystematic and tedious, as they involve many possible types of structures as well as many design variables. Furthermore, electromagnetic (EM) simulators are often used as a complement to general circuit design environment, leading to back-and-forth iterations between different the two environments.
This thesis address these inductor and transformer design problems using design
strategies and tools developed using analytical inductor and transformer models
along with EM-simulations. An optimization method is proposed to design the inductors in a wireless power transfer system involvin...[

Inductors and transformers are essential building blocks in many circuit applications, including wireless power transfer and Radio Frequency (RF) Integrated Circuits (IC). Their design process is often unsystematic and tedious, as they involve many possible types of structures as well as many design variables. Furthermore, electromagnetic (EM) simulators are often used as a complement to general circuit design environment, leading to back-and-forth iterations between different the two environments.
This thesis address these inductor and transformer design problems using design
strategies and tools developed using analytical inductor and transformer models
along with EM-simulations. An optimization method is proposed to design the inductors in a wireless power transfer system involving PCB and on-chip inductors, with measurement results to verify the models used. A design methodology for transformer in impedance matching network is also discussed to aid the design of on-chip transformers, consisting of three design tools: an impedance matching circuit design tool to select the ideal parameters of the transformer, an EM-simulator
based transformer synthesis tool for generating a structure that match the desired
parameters, and a design verification tool that simulate a two-dimensional layout
in a three-dimensional field solver automatically to extract network parameters.
The proposed design methodology is applied in the design of a baseband-over-fiber system that includes a 32 GHz transmitter with 50% fractional bandwidth that impose a stringent requirement to the matching network.
