Hi
I am trying to generate ~50Nano Second negative pulses has anyone any suggestion as to how I would produce these pulses.
Either an individual pulse or a slow stream of pulses would do, less than 10Hz They must be negative and approx 300mV ref to gnd. Any circuit advice?.
These pulses are for test purposes they are going to a ad8561 comparator
Regards.
And thanks for any help

Do you care much about the shape of the pulse?

 

Use a differentiator consisting of a series capacitor followed by a resistor to GND.

 

Hi
Thanks for the reply the shape is not critical. I just need negative pulses
