The effect of circuit parameters of avalanche transistor sweep gener-ators on the sawtooth waveforms is discussed. To improve the sweep linearity, the bootstrap circuit is applied. It is shown that the calculated results are in agreement with experimental data. The avalanche trausistor sine wave oscillators are also studied. Experimental results show that a certain performance of oscillators operated in avalanche mode is found to be letter than that of oscillators operated in normal mode.
