Abstract :
Noise generated by digital sub-circuits becomes serious problem in fast mixed signal systems on chip (SoC). Digitally generated noise corrupts supply voltages and is propagated inside a silicon substrate as so called substrate noise. A discussion and simplified analysis of passive and active circuits for substrate noise suppression is presented in this paper. An example of an active circuit is design and tested by means of simulations. The achieved results show higher efficiency of the active circuits in substrate noise attenuation in comparison to known passive solutions.
