Abstract :
This paper shows UHF oscillations that can occur especially in very soft diodes at the end of the reverse recovery current. The oscillation mechanism is related to that of a BARITT diode. It is possible to simulate the oscillations. The simulation results were in very good agreement with the measurements.
