ABSTRACT:
An integrated circuit includes a p-well block region having a high resistivity due to low doping concentration formed in a region of a substrate for providing noise isolation between a first circuit block and a second circuit block. The integrated circuit further includes a guard region formed surrounding the p-well block region for providing noise isolation between the first circuit block and the second circuit block.
