I,
I am doing a simulation with exponentiel pulse.
Is it possible de repeat the pulses with a frequency
For example, I want one pulse a frequence of 10kHz.
The duration of each exponentiel pulses is 25ns
Thanks

Try using a PIECEWISE_LINEAR_VOLTAGE component. It is easy to make it output any voltage and have it repeat. It is pretty self explanatory, but if you would like to find out more about this functionality, take a look at this page:

Hope that helped

Hi,
Have a look at the attached circuit example. V2 is a Piece Wise Linear (PWL) and you can find this component in the "Sources" group under the "Signal Voltage Sources" family. Double click on this component and you can enter Time vs. Voltage data which controls the output and there is a "Repeat data during simulation" which repeats the pattern. If you look at the PWL output with the scope, you should see a triangle wave because the PWL is connecting the data point you entered.
To get the exponent pulse, you can use an Analog Behaviour Model (ABM) source where you can enter the exponent operator. Double click on ABM source and you can see that I entered "exp(v(2))" and this takes the exponent voltage at node 2.
