Abstract :
The derivation of an efficient Norton equivalent companion GCM for coupled interconnects in high-speed circuits is presented. The proposed model contains fewer nodes compared to its The´venin counterpart and hence accelerates the SPICE solution process. An application example with coupled microstrip lines driven by a bipolar ECL OR gate is given to demonstrate the efficiency. Comparison with the FDTD-SPICE simulation results substantiates the validity of this approach.
