چکیده

An investigation of the effect of substrate loss on simultaneous switqhing noise (SSN) in on-chip power distribution networks is presented. In order to characterize the multi-layered power buses accurately for onship sdtching noise simulation, modeling of VddlGround rails over finite-resistivity substrates should include dielectric loss. The complete circuit model of power rails are then represented using RLCG elements. The waveform and propagation pattern of the noise are captured using finite difference time domain (FDTD) technique. This paper shows the effect of silicon substrate with different resistivities on the propagation of on-chip

Estimation of On-Chip Simultaneous Switching Noise on Signal Delay in Synchronous CMOS Integrated Circuits

On-chip parasitic inductance inherent to the power distribution network has becoming significant in high speed digital circuits. Therefore, current surges result in voltage fluctuations within the power distribution network, creating delay uncertainty. On-chip simultaneous switching noise should therefore be considered when estimating the propagation delay of a CMOS logic gate in high speed syn...
