Hey !
I've been stuck on this problem for quite a while now so i finally ask for some help because i couldnt find any more information on forums or online courses.
I'm currently designing a common emitter amplifier but i don't understand why my base voltage is going negative, if you have any tips helping me for the design or explain to me why this voltage is negative it would be really appreciated.
I try to amplify a rectangle signal (50% duty cycle) 0-5V, this soucre cannot deliver more than 10mA.
I've been using this Instructable tutorial and i'm using LTspice to simulate.
If you have any question or need more information tell me i will give it to you asap.
Thank you for your help
The simulation file is linked to this post, don't pay attention to the components on the side (not on the screen).
