Abstract

In this paper, we discuss generation of digital switching noise and its propagation through substrate and interconnection parasitics. Effects of switching noise on analog voltage references and radio-frequency blocks are presented. Both simulated and measured results confirmed that crosstalk effects are strongly dependent on substrate and package type. Isolation strategies must be specifically designed for a mixed-signal chip, as they could even worse crosstalk if they are not properly designed accounting for values of parasitics.
