| Abstract: | A 24 V pulse step of less than 70 ps risetime is obtained from a pulse-sharpening circuit using step-recovery diodes. The initial pulse is generated by an avalanche transistor. Super-position of two opposite steps, appropriately delayed, yields a pulse of variable duration between 150 ps and 20 ns at constant amplitude. |
