A logic gate drives a load, which has a resistance of 1 kΩ and a capacitance of 20 pF. The printed circuit track connecting the gate to its load has an 40 pF capacitance to ground. The output changes state from 2.5 V to 0 V in 200 ps.
Determine the maximum output current to find the the initial surge of current for (a) use I=C*dv/dt.
