I need some help with a single stage BJT amp. I need to get some considerable current gain (18.5 A/A) from this stage as well as deliver 5 mA peak-to-peak to a load resistance.

I wanted to initially go for a common-collector configuration, but I have this 2 kΩ resistor at the collector that has to be there (I need an output resistance of exactly 2 kΩ). What other configurations are there that I could consider that could give me high current gain (as well as some stability to changes β)?

I really appreciate the help. I'll post a schematic in a minute. I am having some trouble posting it with this thread.

Some important parameters:

Vcc = 20 V

Source resistance = 15 kilo ohms

Beta = 225

Capacitors are "large"
