Abstract:
1. A computer-implemented method for determining s-parameters of components in a printed circuit board (PCB) channel, comprising: receiving, using a computer, measured s-parameters for a first PCB channel, the first PCB channel including a first trace having a component coupled to each end, the components being substantially identical to each other such that the first PCB channel is symmetrical about the center of the first trace; receiving, using the computer, measured s-parameters for a second PCB channel, the second PCB channel including a second trace having a component coupled to each end, the components being substantially identical to each other and to the components of the first PCB channel such that the second PCB channel is symmetrical about the center of the second trace, wherein the first trace has a length differing from a length of the second trace; and determining, using the computer, calculated s-parameters for the first trace, the second trace, and the components using the measured s-parameters for the first and second PCB channels by applying stochastic optimization to the measured s-parameters for the first and second PCB channels to determine s-matrices of the components by searching a multi-dimensional parameter space.
