Simultaneous switching output

WebbWhen multiple output drivers switch simultaneously, they induce a voltage drop in the chip or package power distribution. The simultaneous switching momentarily raises the ground voltage within the device relative to the system ground. This apparent shift in the ground potential to a nonzero value is known as Simultaneous Switching WebbII.a. Multiple output drivers The ground bounce can become very large when multiple out-put drivers switch simultaneously. In this case the ground bounce equation is obtained for a single driver with a modified gain parameter, βn,eq which is the summation of the gain param-eters of individual drivers. In reality not all the drivers switch
