@@@@The transmission and suppression of the simultaneous switching noise (SSN) are investigated based on microwave network principle. A new method for the suppression of the noise transmission with multi-stage capacitors is presented in this paper. The design rules of the method with multi-stage capacitors are derived. The simulation results show that using the multi-row distributed capacitors and increasing transmission loss of noise path could improve the ability to suppress the noise transmission and increase the efficiency of the noise suppression with capacitors. Finally, the performance of the method is verified with finite difference time domain(FDTD) simulations and measured results.
