Exponential waveform

You can periodically charge and discharge a capacitor through a resistor using a pulse source.
 
Hi

Use an EXP voltage source and trigger it with a second voltage source.
Set the trigger voltage source "cycles" for the desired number of cycles.
See example attached.

It works fine on my system. Make sure your running the latest version of LTspice.
Else, attach your ,asc file and I will test.
 
Hi eTECh
Already updated my version of LT Spice , still its not working . I will attach the .asc file for your reference

Hi

The problem with your schematic is that the TRIGGER statement is not entered as part of the EXP statement. You've added it to the schematic as a separate statement.
To fix this:

1. Delete the "TRIGGER" statement
2. Rht-click the "EXP" text on the schematic, then add the TRIGGER statement at the end of the EXP statement. Then click OK.

I've attached a corrected version of the schematic.
