Hi, just for fun and educational purpose, I'm doing some schematic simulation on LTSpice and Multisim Blue. Well, thanks to these software I am able to simulate and then build some basic and simple circuit. But I encountered some trouble:
Take a look to the attached image:
This is a simple triangle wave generator based on an NE555: in the simulation I attempted to insert a transistor to amplify/boost the output signal, but indiscriminately by the value of the components (resistors and the kind of transistor) I got a weird output, which go from 41mV to 65mV. All is fine and acts as expected if I remove the transistor. I encountered this trouble also using Multisim, but the strange result is always the same also if I change the kind of transistor and the base resistor.
Some hints? I'm just doing something's wrong?
Thank you.
