Hi there
In the above simulation, the only change than I have done is increasing the resistance to have a higher gain. I did not understand if you pointed out to this change or you meant something else. Please let me know in detail what I need to change.
But why? For sure changing the gain will modify timing and waveform.
We are now at post #44. Two and a half weeks...
Ask yourself: Does it improve circuit performance? Does it speed up progress? Does it motivate to help?
