(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I am designing a voltage divider common emitter amplifier given the following parameters

Av= 40 dB +/- 1dB

Zi> 1000 ohms

Zout< 5000 ohms

Stability factor = 5

Beta*re= 650 ohms

Beta minimum = 35

Beta maximum = 300

Vcc = 20 volts

Rload = 33 kilo-ohms

Rsource = 470 ohms

Vce= 10 volts

Ve= 2 volts

We can use the approximation that Ic=Ie

My teacher has given us a "hint" saying to work backwards from the AC analysis.

I need to solve for Re, R1, R2, Rc and the respective currents.

I am lost as to where to start with this circuit.

2. Relevant equations[/b

Ic=Ie

Ib=Beta*Ic

Vb=(Vcc(R2))/(R1+R2)

Vcc-Vce-Ic(Re+Rc)=0

re=(26*10^-3)/Ic

Stability Factor=Rthevenin/Re

Av in db=20log(Vo/Vi)

3. The attempt at a solution

I am completely lost where to start with this circuit. So I have not attempted it.
