bjts

Hi everyone, I have been researching this topic for the last seven months without success and this is the first time I have posted on a forum asking for help. I have no training in electronics. I work as a sculptor and have started integrating "simple" (although, not for me) electronics into...

Hello, I can't seem to find the first all BJT audio amplifier. When and who invented it?

Hello, I am studying digital electronics and I am a bit confused about the saturation conditions of the bjt. I knew that the bjt saturates when the Vce is close to 0 and Vbe >= 0.7. However, when I was reading about TTL I got confused. Can someone give me some intuition and explain me why in the...

I know Cmeu is parasitic capacitance in active mode. It's the B-C junction capacitance. But does it change when the npn is operating in saturation mode? Also in general(not just in saturation mode) what happens to Cmeu at increasing Vce? Does it increase? What other things happen to the...
