Abstract :
In this letter, we propose a general method based on the modified nodal approach (MNA) to incorporate packaged diodes into finite-difference time-domain (FDTD) method with diodes spanning multiple FDTD cells. The approach to fill the extended nodal matrix can be applied to analyze circuits with different topologies. The validity of this method is demonstrated by connecting a packaged diode, MA4E1317, at the end of a microstrip transmission line, which spans three and nine FDTD cells, respectively. Results are in good agreement with those obtained by the commercial circuit simulation package ADS.
