Abstract :
A new circuital non-linear continuous model for hysteretic comparators is proposed. Using this model, SPICE simulations of hysteretic DC-to-DC switching converters can provide both time and frequency analysis. Faster transient simulations are another benefit of the non-linear continuous circuital model. The new continuous model has been validated by means of PSpice simulations of hysteretic controlled buck and boost converters. Time-transient results of an exact switched approach have been compared with the plots obtained using the new proposed model. Frequency simulations are compared with Bode plots obtained by means of a classical small-signal linear analysis.
