February 28, 2019Inside Signal Integrity: Impedance Control - Part 2
In part 1 of this blog we took a back-to-basics approach and discussed line impedance and its effects in signal integrity. As every electrical conductor comprises capacitance, an inductance, and a frequency-dependent ohmic resistance, and with increasing frequencies, these electrical characteristics will influence and distort the signal.

Impedance and impedance control are some of the oldest and most discussed topics in PCB design. They are especially important in high-speed design related to signal integrity. In this, the first of a two-part blog, we’ll go back to the basics of impedance/impedance control and consider what influences line impedance. In part two, we’ll set about controlling it.
