See first figure attached.

2. Relevant equations

3. The attempt at a solution

See 2nd figure attached for my work so far at attempting the design.

The last figure is what my textbook gives as the small signal analysis of a BJT differential amplifier with emitter resistances. However, this may be a little different than our design because we replace the current source with a single resistor.

I'm little overwhelmed and I'm not really sure where to start with this design.

I know that for a differential amplifier with resistances in the emitter leads the differential gain is given by,

[tex]A_{d} = \frac{\alpha(2R_{c})}{2r_{e} + 2R_{e}} \approx \frac{R_{c}}{r_{e} + R_{e}}[/tex]

Are there any other parameters in my design that I can currently establish, so that the number of things I have to solve for is diminished? What should I work with first? What other equations do I need to concern myself with?

Thanks again!
