Hi guys,
I am trying to build a Pulse Generator which generates a 1us pulse (no variation in the length of the pulse) but the frequency should be variable between 0.2 and 20kHz and the voltage output is ought to be between 0V and 30V on a 50 Ohm load impedance.
The difficulty I have atm is that the Rise/Fall Time should be 5ns. Unfortunately I will not be able to use a 555 Timer because the Jitter is too high on those ICs.
I came across two different possibilities of creating such a circuit. The first one is using a Shock Line Pulse Generator but this seems to mostly apply to high voltage applications. Secondly it would be possible to use Differential Amplifiers but these seem to have a "slow" slew rate for my application.
Any ideas on what method I should apply?
Thanks for your input
