multistage

I have been tasked to design a multistage amplifier with the following specifications: Gain(V/V) = 30, Rin = 20 kohms, Rout < 25 ohms, Power supply = Dual +12V -12V, Max Symmetrical Swing > 9Vpp (peak-to-peak), lower 3dB down point < 200 Hz, Upper 3dB down point > 5 kHz, Rload = 200 ohms. I...

I had been trying to create a BJT Multistage Amplifier circuit which had a total voltage gain of -40. The problem is whenever I tried to calculate the value starting from the total voltage gain it always goes wrong and totally different comparing the simulations and calculations. Anyone can help...
