Abstract :
In This paper three optimization methods of ground design are used to solve EMI problems on the PCB mixed with both analog and digital signals. A model was built to test the surface current, E field, H field and S-parameters of the circuit board to consider the effect of these methods of avoiding EMI and SI problems. Then simulation experiments on a real product are carried out to show the improved performances after adopting these methods.
