Abstract
The thesis focuses on eye diagram improvement using reflections caused by impedance mismatch for lossy lines. When signal transmits at high speed, the loss that comes from the transmission line increases. In order to avoid the resultant voltage waveform distortion the misjudgment of digital signal, and even system failure, utilizes the superposition of reflection by high impedance line to improve the signal integrity of the wave form at receiver.
In addition, this study utilizes an inductor or a high impedance line as the high impedance component and investigates its performance. A set of design rule has been derived for inductance value and length of high impedance transmission line. Given the frequency dependence of the transmission line loss, one can find out accurately the desired compensation. This may not only improve the signal integrity, but also save the time of simulation and design.
