See the first figure attached for the design we are attempting to achieve.
The second figure attached is my work so far on 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,
\(A_{d} = \frac{\alpha(2R_{c})}{2r_{e} + 2R_{e}} \approx \frac{R_{c}}{r_{e} + R_{e}}\)
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!
