Abstract :
Frequency-domain S-parameter measurement techniques are used to establish the high-frequency/high-speed equivalent circuit models of enhanced ball grid array packages. By considering the longest coupled traces of the packages, the coupled transmission-line parameters found include the characteristic impedance, coupling coefficient and propagation delay. The equivalent lumped models have been further derived from coupled transmission line models using the concept of distributed circuits
