Abstract :
A time-domain characteristic model (TDCM) of two-port interconnects considered as linear networks is presented. A time-domain iteration algorithm based on waveform relaxation and deconvolution techniques is employed to synthesize the model from the time-domain measured data of response voltages of the interconnects with step excitation and resistor load. This procedure is applied to extract the TDCM functions for two cascaded microstrip steps to illustrate its efficiency. Then, the extracted model is used to simulate the response of the structure terminated by a resistor and a capacitor, respectively. The simulated results are compared with the measured data to validate the accuracy of the model
