Recent electronic system has extra high clock frequencies over GHz. This leads to high transmission speed on the printed circuit-board.
In this situation, the system being designed without knowing the high-frequency phenomena, may cause malfunction. In this
lecture, signal integrity for high-speed digital designs are discussed. Especially, signal reflection and loss, crosstalk
mechanism, and impedance matching techniques by using Smith Chart are discussed in detail.
High-speed systems being designed without knowing high-frequency phenomena may cause serious malfunction. So, high-speed system
designers should have knowledge of techniques to prevent signal waveform deterioration at high frequencies.
