Hi
I have a question about differential amplifier.
I`ve designed a differential ampli with two pnp transistors
those are bc807-40 .I had never worked with a pnp tran before.
the question is getting the most possibe gain from the circuit.
as you see in te pictures I have connected a current mirror as
a current source under the tho emitters.
I have two Rc with the value of 21 k.and because my current mirror is giving me
1.221 mili Am those Rc were the highest I could put there not allowing
the transistors to go to saturation.
Was my design correct or you see problems in that?
do you have any Idea to make the gain higher?
the schematic of my circuit is below:
I look forward to your guidance.
