A multi-path structure is proposed for reduction in effect of digital substrate noise which degrades analog circuit performance. As an example low-pass filters are implemented in a 0.18-µm CMOS process. 11-dBm reduction in digital substrate noise is achieved as compared with a conventional structure.
