Two stage amplifer

[low hoi suan]

can u design a multi-stage BJT amplifier
1.Total supply voltage: 12 V – 15 V
2.Input signal voltage: 8 mVp
3.Gain: 37 dB – 39 dB
4.Lower cut-off frequency: 0 – 300 Hz
5.Upper cut-off frequency: 700 kHz – 12 MHz
6.Load resistance: 16 Ω
7.Total power consumption: < 5 W

My upper cut off frequency cant near to zero

I understand 4. so that you can either design a DC coupled amplifier (lower cut-off 0 Hz) or an AC coupled amplifier. As we specify cut-off frequency usually for -3 dB gain drop, the shown transfer function has a lower cut-off of about 1 kHz and doesn't fulfill the spec.

You should design a DC Coupled Amplifier for lower frequencies.
