You can use an op amp in this case with good results.
Hello,
So you need a gain of 40 V/V.
What input resistance is required?
What output resistance is required?

Then you have to build a common emitter amplifier with a gain of 40V/V and then fed its output to the input of an emitter follower to achieve low output impedance.
The gain of a CC is about 1.Can you please show me the connection
because I tried this configuration (CE-CC) in the PSpice & the gain is approximately = 1
Hello,
That could be made with a two stage amplifier.
At the input a mosfet for the high input resistance and gain.
Afther that an emmitter follower for the low output resistance.
Greetings,
Bertus
This is true about the voltage gain.The rule says:
The gain of a multistage amplifier is the gain product of each BJT
This is true about the voltage gain.
For the current gain you cannot simply multiply the individual current gains.
