ABSTRACT:
Method and system for enhancing RF immunity of integrated circuits (ICs). Susceptibility of different subcircuits within the IC is determined by simulation or bench testing. Relatively simple filters are implemented based on the susceptible frequency range and circuit parameters such as impedance. Filter(s) may be integrated into the IC avoiding PCB level redesign. Susceptibility determination and mitigation method may be applied to new IC designs or existing ICs without major redesign.
