I am having a problem building a simple amplifier using a TIP31C transistor.
I actually succeeded before with different transistors, but I can't seem to get this to work.
I am trying to amplify a signal of about 1V up to 50V, but if I could just get an amplification of 10x I would be happy as I could always add another stage to get the final result.
The source voltage is 100V, but I do not want more than 10mA of current, preferably less. So I start with a collector resistance of 10k.
I need to know the emitter resistance and the two resistors to the base (for biasing). I have a book and went through the process given, but it didn't work. I also tried some ideas from the internet, but they didn't work either.
I played around with it and got some amplification, but with lower collector resistance and it drew too much current.
Does anyone know if this could work and what resistance there should be in the other three resistors (when the collector resistance is 10k)?
I am sorry to ask as this is probably really simple, but I just can't seem to get it.
