Hey guys,
This is my first post. I am wrapping up a BJT CE amplifier project. Here are the parameters:
DC Power Consumption <= 30mW
Overall Gain (open circuit gain= no load resistor, right?) = 80 V/V
Less than 10% change in Icq if Beta varies between 100 to 200
Overall Swing of 8Vp-p with rails (GND to 15V)
*I'm using a 2N3904
I pretty much have all of the parameters met(let me know if I don't plz) but what I'm confused about is why I had to but a small resistor in series with my bypass capacitor.
I came to the conclusion that I needed this from students previously taking the class. I was getting serious clipping without it. But I'm frustrated that I can't calculate it.
What I'm asking for is just a basic description of why this works and if there is a way I can calculate this.
Thanks for this forum,
Mike
