| Summary: | 碩士 === 國立交通大學 === 光電工程所 === 88 === The small signal equivalent circuit, packaging effects and high-speed characteristics of the PIN diode are investigated in this thesis. We demonstrate a typical small signal equivalent circuit of the PIN diode based on the device physics. By introducing the concept of a distributed RC effect into the model, we can obtain better extracting circuit parameters. As a result, the error of the optimization extracting parameters can be within 1%. In addition, for the TO-can package which is commonly used nowadays, we tentatively use a rough circuit model to define it and investigate the possible effects. The experiments exhibit the limit of TO-can package under high-speed operation. The high-speed characteristics of the hybrid PIN-FET are also presented.
