The power circuit of the CPU core voltage must be checked to ensure system stability for high
speed CPUs (such as the new Pentium III, or when overclocking). A typical CPU core voltage is
2.0V, so a good design should control voltage between 1.860V and 2.140V. That is, the transient
must be below 280mV. Below is a timing diagram captured by a Digital Storage Scope, it shows the
voltage transient is only 143mv even when maximum 18A current is applied.
