Measurement of milliohms of impedance at hundred MHz on chip power supply loop

The introduced method of measuring the high frequency impedance of a microprocessors power supply loop is based on measurement of the on-chip voltage generated by a predetermined stimulus formed by a set of computer instructions.

Modeling and measurement of the Alpha 21364 package

The latest generation Alpha microprocessor, the 21364, uses a ceramic LGA package with mesh power and ground planes. Electromagnetic modeling and measurements were used to verify the validity of the design of the package, and to suggest improvements to the layout to minimize crosstalk.
