Abstract :
A parallel resonant circuit representing the small-signal behaviour of the avalanche region of IMPATT diodes is given. The components are calculated in a nonquasistatic manner for different ionisation rates and drift velocities of electrons and holes. With the results, the avalanche frequencies of Si, Ge and GaAs as functions of the avalanche zone width are compared.
