Abstract :
A novel time adaptive time-domain technique based on the Haar expansion basis is proposed and validated for a specific circuit problem. The modeling of active and passive lumped and distributed elements, as well as of excitation and boundary conditions, is performed effectively. This scheme, based on a combination of absolute and relative thresholding, provides a real-time time adaptive grid with improved time resolution in comparison to conventional time-domain schemes (FDTD) while maintaining a similar accuracy
