Abstract :
A MOSFET model with more realistic micron-size physical dimensions is incorporated in the FD-TLM method, expanding the application of this full-wave electromagnetic field calculation method to new systems. Good agreement is obtained between finite difference-transmission line matrix (FD-TLM) and SPICE3 simulations of a CMOS inverter, validating the MOSFET implementation in the FD-TLM method. Structural dimensions are intentionally made small compared to the wavelength of signals so that SPICE3, a quasi-static-based circuit analysis program, can be used for validation.
