Nonlinear circuits are a key component in RF transceivers. Efficiency and power requirements for 5G communication are creating new challenges in simulation and modeling of nonlinear devices. An application of the finite-difference time-domain (FDTD) method to nonlinear circuits comprising diodes is demonstrated. A frequency multiplier is constructed from a diode and a low-pass filter. The diode is simulated in the context of this circuit to demonstrate the formation of harmonics.

Abstract. An interconnection system whose loads protected by a voltage suppressor and a low-pass filter against overvoltages caused by coupling pulse-shaped electromagnetic waves is analyzed. The external wave influencing the system is assumed as a plane wave with HPM form. The computation is provided by a full-wave PEEC model for the interconnection structure incorporated in the SPICE code. Thus, nonlinear elements of the protection circuit can be included in the calculation. The analysis shows intermodulation distortions and penetrations of low frequency interferences caused by intermodulations through the protection circuits. The example examined shows the necessity of using full-wave models for interconnections together with non-linear circuit solvers for simulation of noise immunity in systems protected by nonlinear devices.
