The inductive effect of a printed-circuit board (PCB) trace can be reduced by bypassing. Careful
layout procedures should be observed to minimize inductance. Figure 10-2 shows methods for
reducing the inductive effects of PCB traces. The power and ground trace layout has a low resis-
tance. This is because the loop area between the integrated circuits (ICs) and the decoupling ca-
pacitors is small and the power and ground traces are physically close. This results in lower
characteristic impedance, which in turn reduces the line voltage drop.
