MEASUREMENT-BASED LARGE-SIGNAL DIODE MODELING SYSTEM FOR CIRCUIT AND DEVICE DESIGN

A new relaxation-time large-signal table-based diode model for circuit simulation and an associated automated system which characterizes the device and generates the model data file, are presented. Excellent ag reement between simulated and measured fundamental and second through fourth harmonic power levels is demonstrated for a HEMT diode up to fr equencies of 48 GHz. Excellent agreement is demonstrated between simul ated and measured large-signal oscillation frequency versus varactor t uning voltage for a varactor-tuned oscillator circuit fabricated with a varactor diode designed using the model.
