High-voltage picosecond pulse generation using avalanche diodes

The generation ofkilovolt-level sub-lOOps wide pulses using the avalanche transit-time effect in abruptjunction P-i-NN+ silicon diodes is described and the basic theory for this " single-shot" mode of the microwave TRAPATF oscillator is discussed. We then present a computationally efficient SPICE model and compare simulations to lab data for two basic circuit configurations. 1.
