Narrow pulse signal generation is an important part in high-speed systems design. Utilizing the voltage and current phase difference of inductor and diode, a very short pulse can be generated from a sinusoidal voltage source. Such systems usually include highly nonlinear components and complicated three-dimensional structures. Dispersion, field effects and the interaction between electromagnetic field and components cannot be ignored in the simulation of these electrically small and complicated systems. Therefore, time-domain and full-wave analysis is necessary. This paper presents a full wave FDTD analysis using an improved field-circuit model for hybrid system simulation, which includes both lumped elements and field effect. Two and three-dimensional hybrid (distributed and lumped) circuits are constructed and analyzed in this paper to demonstrate the versatility of the time-domain simulator.
