Hey guys.
I have an assignment which presents to me a basic BJT amplifer circuit that looks similar to this:
I've drawn it up in a circuit simulator, and no matter how I play with it, it is always inverting. Is this correct? I have fiddled with the VCC and VEE values, as well as all the resistor values.
Here's my problem though. My teacher has asked me to design an amplifier using this configuration to have a gain of greater than or equal to 30db. But how can you have this if the output is always negative? Doesn't this mean in your gain calculations it's always going to be negative?
I'm stuck
Regards,
Andrew
