I have to build an amplifier that have the following spec
1. Use two BJT blocks(attached)
2. signal source is sin voltage with 10K source resistance. Output is 100mV peak-to-peak sin with any DC offset. Midband voltage gain should be more than 10. Output load is a 1k resistor
3. Power supply: up to +15 and -15
4. The important part of the amplifier is that it should maximize gain bandwidth product
5. Of course, I can add as many resistors/cap as I want.
The BJT I use are Fairchild's 2N3904 IC.
What design should I use?
Currently, I'm thinking about a common-base - common-emmiter cascode.
*Edit: in the previous diagram, the unit for the capacitors had been mistakenly change from nF to uF
