A circuit supplies a 'square' current waveform, with a peak value of 25 mA and transition times of 10 ns, as shown in FIGURE 3. The ground return conductor has a resistance of 50 mΩ and an inductance of 100 nH.
(a) Determine the maximum voltage drop along the ground conductor.
(b) Sketch the waveform of the voltage which will appear along the ground conductor.
(c) How would you reduce the ground conductor impedance in practical circuits?

The solution covers in detail the dynamics of a voltage drop when a current pulse is applied to the ground conductor. In addition, some hints are given for the design of practical ground conductors.
