Abstract :
Digital noise in mixed-signal circuits is characterized using a scalable macromodel for substrate noise coupling. The noise coupling obtained through simulations is verified with measured data from a digital noise generator and noise sensitive analog circuits fabricated in the 0.35-μm heavily doped CMOS process. The simulations and measurements also demonstrate the effectiveness of including grounded guard rings and separating bulk and supply pins in digital circuits to reduce substrate coupling.
