Abstract
An integrated circuit formed within a substrate has a first circuit section and an active noise cancellation section located at least between the first circuit section and a noise source. The active noise cancellation section is coupled to the substrate and injects counter-charge into the substrate to isolate the first circuit section from noise produced by the noise source.
