Patent ID: 7741857

Claim:
A system for extracting pad set parasitics from a device test structure (DTS), said system comprising: said DTS embedding a device under test (DUT); at least one calibration standard for said DUT; scattering parameter (S-parameter) measurement means for measuring S-parameters of said DTS and said at least one calibration standard at multiple frequencies; a parameterized netlist representing said pad set parasitics and containing a lumped element network having at least one parameterized lumped element; S-parameter fitting means for fitting measured S-parameters of said DTS and said at least one calibration standard with said at least one parameterized lumped element; 4-port Y-parameter calculation means for calculating a 4-port Y-parameter of said parameterized netlist from a fitted parameterized lumped element value for each of said at least one parameterized lumped element; and 4-port de-embedding calculation means for extracting a 2-port Y-parameter of said DUT using said 4-port Y-parameter of the parameterized netlist.
