WitrynaBased on the fact that the avalanche frequency of impact-ionization avalanche transit-time (IMPATT) diode is proportional to the square-root of DC biasing current density, more DC current injection is necessary to push the negative differential resistances (NDRs) into higher frequency regime. This leads to a serious thermal endurance … WitrynaFigure 5.1: Symbolized process of a pure electron induced impact-ionization avalanche generation. After an electron is accelerated along an average distance it undergoes a collision and the excess energy …
